RTX Options

RTX Options are configurable parameters for RTX pipeline components. They can be set via rtx.conf in a following format:

<RTX Option int scalar> = <Integer value>
<RTX Option float scalar> = <Floating point value>
<RTX Option int vector> = <Integer value>, <Integer value>, ...
<RTX Option float vector> = <Floating point value>, <Floating point value>, ...
<RTX Option boolean> = True/False
<RTX Option string> = <String value, no quotes>
<RTX Option hash set/vector> = <Hex string>, <Hex string>, ...

Practical examples of syntax:

rtx.someIntScalar = 38
rtx.someFloatScalar = 29.39
rtx.someIntVector = 1, -2, 3
rtx.someFloatVector = 1.0, -2.0, 3.0
rtx.someBoolean = True
# Note: Leading whitespace in a string is removed, allowing for nicer option formatting like this without messing up the string.
# Additionally, strings should not be surrounded with quotes as these will be treated as part of the string.
rtx.someString = This is a string
# Note: 0x prefix on hash hex values here is optional, similarly these values are case-insensitive. 16 hex characters = 64 bit hash.
rtx.someHashSet = 8DD6F568BD126398, EEF8EFD4B8A1B2A5, ...

RTX Options may be set in multiple places, specifically a hardcoded set in src/util/config/config.cpp which is assigned per-application based on process name, and the two user-configurable files dxvk.conf and rtx.conf. If not set the options will inherit their default values. The full order of precedence for how each set of options overrides the previous is as follows:

Default option value (Implicit)
dxvk.conf ("User Config")
Per-application config.cpp configuration ("Built-in Config")
rtx.conf ("RTX User Config")
baseGameModPath/rtx.conf (Mod-specific extension of "RTX User Config")

Additionally, upon saving options from the Remix UI options are written only to rtx.conf.

Tables below enumerate all the options and their defaults set by RTX Remix. Note that this information is auto-generated by the RTX Remix application. To re-generate this file, run Remix with DXVK_DOCUMENTATION_WRITE_RTX_OPTIONS_MD=1 defined in the environment variables.

Simple Types

RTX Option	Type	Default Value	Description
rtx.adaptiveAccumulation	bool	True
rtx.adaptiveResolutionDenoising	bool	True
rtx.adaptiveResolutionReservedGPUMemoryGiB	int	2	The amount of GPU memory in gibibytes to reserve away from consideration for adaptive resolution replacement textures. This value should only be changed to reflect the estimated amount of memory Remix itself consumes on the GPU (aside from texture loading, mostly from rendering-related buffers) and should not be changed otherwise. Only relevant when force high resolution replacement textures is disabled and adaptive resolution replacement textures is enabled. See asset estimated size parameter for more information.
rtx.allowCubemaps	bool	False	When enabled, cubemaps from the game are processed through Remix, but they may not render correctly.
rtx.allowFSE	bool	False	A flag indicating if the application should be able to utilize exclusive full screen mode when set to true, otherwise force it to be disabled when set to false. Exclusive full screen may see performance benefits over other fullscreen modes at the cost of stability in some cases. Do note that on modern Windows full screen optimizations will likely be used regardless which in most cases results in performance similar to exclusive full screen even when it is not in use.
rtx.alwaysCopyDecalGeometries	bool	True	When set to True tells the geometry processor to always copy decals geometry. This is an optimization flag to experiment with when rtx.useBuffersDirectly is True.
rtx.alwaysWaitForAsyncTextures	bool	False
rtx.antiCulling.light.enable	bool	False	Enable Anti-Culling for lights.
rtx.antiCulling.light.fovScale	float	1	Scalar of the FOV of lights Anti-Culling Frustum.
rtx.antiCulling.light.numFramesToExtendLightLifetime	int	1000	Maximum number of frames to keep when Anti-Culling is enabled. Make sure not to set this too low (then the anti-culling won't work), nor too high (which will hurt the performance).
rtx.antiCulling.light.numLightsToKeep	int	1000	Maximum number of lights to keep when Anti-Culling is enabled.
rtx.antiCulling.object.enable	bool	False	Extends lifetime of objects that go outside the camera frustum (anti-culling frustum).

This method is slightly expensive but it effectively addresses object flickering issues that arise from corner cases in the fast intersection check method. Typically, it's advisable to enable this option unless it results in a notable performance drop; otherwise, the presence of flickering artifacts could significantly diminish the overall image quality.
rtx.antiCulling.object.enableInfinityFarFrustum	bool	False	Enable infinity far plane frustum for anti-culling.
rtx.antiCulling.object.farPlaneScale	float	10	Scale applied to the far plane for Anti-Culling Frustum for matching the culling frustum in the original game.
rtx.antiCulling.object.fovScale	float	1	Scale applied to the FOV of Anti-Culling Frustum for matching the culling frustum in the original game.
rtx.antiCulling.object.hashInstanceWithBoundingBoxHash	bool	True	Hash instances with bounding box hash for object duplication check. Disable this when the game using primitive culling which may cause flickering.
rtx.antiCulling.object.numObjectsToKeep	int	10000	The maximum number of RayTracing instances to keep when Anti-Culling is enabled.
rtx.applicationId	int	102100511	Used to uniquely identify the application to DLSS. Generally should not be changed without good reason.
rtx.asyncTextureUploadPreloadMips	int	8
rtx.autoExposure.autoExposureSpeed	float	5	Average exposure changing speed (in units per second) when the image changes.

rtx.autoExposure.evMinValue	float	-2	Min/Max values tuned by moving from bright/dark locations in game, and adjusting until they look correct.
rtx.autoExposure.exposureAverageMode	int	1	Average mode. Valid values: <Mean=0, Median=1>. The mean mode averages exposures across pixels. The median mode is more stable for extreme pixel values.
rtx.autoExposure.exposureCenterMeteringEnabled	bool	False	Gives higher weight to pixels around the screen center.
rtx.autoExposure.exposureWeightCurve0	float	1	Curve control point 0.
rtx.autoExposure.exposureWeightCurve1	float	1	Curve control point 1.

rtx.automation.disableBlockingDialogBoxes	bool	False	Disables various blocking blocking dialog boxes (such as popup windows) requiring user interaction when set to true, otherwise uses default behavior when set to false. This option is typically meant for automation-driven execution of Remix where such dialog boxes if present may cause the application to hang due to blocking waiting for user input.
rtx.automation.disableDisplayMemoryStatistics	bool	False	Disables display of memory statistics in the Remix window. This option is typically meant for automation of tests for which we don't want non-deterministic runtime memory statistics to be shown in GUI that is included as part of test image output.
rtx.automation.disableUpdateUpscaleFromDlssPreset	bool	False	Disables updating upscaler from DLSS preset. This option is typically meant for automation of tests for which we don't want upscaler to be updated based on a DLSS preset.
rtx.automation.suppressAssetLoadingErrors	bool	False	Suppresses asset loading errors by turning them into warnings. This option is typically meant for automation of tests for which acceptable asset loading issues are known.
rtx.blockInputToGameInUI	bool	True
rtx.bloom.enable	bool	True
rtx.bloom.intensity	float	0.06
rtx.bloom.sigma	float	0.1
rtx.calculateLightIntensityUsingLeastSquares	bool	True	Enable usage of least squares for approximating a light's falloff curve rather than a more basic single point approach. This will generally result in more accurate matching of the original application's custom light attenuation curves, especially with non physically based linear-style attenuation.
rtx.camera.enableFreeCamera	bool	False	Enables free camera.

rtx.cameraSequence.mode	int	0	Current mode.
rtx.cameraShakePeriod	int	20	Period of the free camera's animation.
rtx.capture.correctBakedTransforms	bool	False	Some games bake world transforms into mesh vertices. If individually captured meshes appear to be way off in the middle of nowhere OR instanced meshes appear to all have identity xform matrices, enabling will attempt to correct this and improve stage + mesh viewability in tools. Hashes are unaffected.
rtx.captureDebugImage	bool	False
rtx.captureEnableMultiframe	bool	False	Enables multi-frame capturing. THIS HAS NOT BEEN MAINTAINED AND SHOULD BE USED WITH EXTREME CAUTION.
rtx.captureFramesPerSecond	int	24	Playback rate marked in the USD stage. Will eventually determine frequency with which game state is captured and written. Currently every frame -- even those at higher frame rates -- are recorded.
rtx.captureHotKey	unknown type	unknown type	Hotkey to trigger a capture without bringing up the menu.
rtx.captureInstances	bool	True	If true, an instanced snapshot of the game scene will be captured and exported to a USD stage, in addition to all meshes, textures, materials, etc. If false, only meshes, etc will be captured.
rtx.captureMaxFrames	int	1	Max frames capturable when running a multi-frame capture. The capture can be toggled to completion manually.
rtx.captureMeshBlendWeightDelta	float	0.01	Inter-frame blend weight min delta warrants new time sample.
rtx.captureMeshColorDelta	float	0.3	Inter-frame color min delta warrants new time sample.
rtx.captureMeshNormalDelta	float	0.3	Inter-frame normal min delta warrants new time sample.
rtx.captureMeshPositionDelta	float	0.3	Inter-frame position min delta warrants new time sample.
rtx.captureMeshTexcoordDelta	float	0.3	Inter-frame texcoord min delta warrants new time sample.
rtx.captureNoInstance	bool	False	Same as 'rtx.captureInstances' except inverse. This is the original/old variant, and will be deprecated, however is still functional.
rtx.captureShowMenuOnHotkey	bool	True	If true, then the capture menu will appear whenever one of the capture hotkeys are pressed. A capture MUST be started by using a button in the menu, in that case. If false, the hotkeys behave as expected. The user must manually open the menu in order to change any values.
rtx.compositePrimaryDirectDiffuse	bool	True	Enables direct lightning's diffuse signal for primary surfaces in the final composite.
rtx.compositePrimaryDirectSpecular	bool	True	Enables direct lightning's specular signal for primary surfaces in the final composite.
rtx.compositePrimaryIndirectDiffuse	bool	True	Enables indirect lightning's diffuse signal for primary surfaces in the final composite.
rtx.compositePrimaryIndirectSpecular	bool	True	Enables indirect lightning's specular signal for primary surfaces in the final composite.
rtx.compositeSecondaryCombinedDiffuse	bool	True	Enables combined direct and indirect lightning's diffuse signal for secondary surfaces in the final composite.
rtx.compositeSecondaryCombinedSpecular	bool	True	Enables combined direct and indirect lightning's specular signal for secondary surfaces in the final composite.
rtx.debugView.composite.compositeViewIdx	int	0	Index of a composite view to show when Composite Debug View is enabled. The index must be a a valid value from CompositeDebugView enumeration. Value of 0 disables Composite Debug View.
rtx.debugView.debugViewIdx	int	0	Index of a debug view to show when Debug View is enabled. The index must be a valid value from DEBUG_VIEW_* macro defined indices. Value of 0 disables Debug View.
rtx.debugView.displayType	int	0	The display type to use for visualizing debug view input values. Supported display types are: 0 = Standard, 1 = BGR Exclusive Color, 2 = EV100, 3 = HDR Waveform Each mode may be useful for a different kind of visualization, though Standard is typically the most common mode to use. Standard mode works for a simple direct, scaled or color mapped visualization, BGR exclusive for another type of color mapped visualization, and EV100 or the HDR Waveform for understanding HDR value magnitudes in the input on a log scale.
rtx.debugView.enableAccumulation	bool	False	Enables accumulation of debug ouptput's result to emulate multiple samples per pixel or over time.
rtx.debugView.enableContinuousAccumulation	bool	True	Enables continuous accumulation even after numberOfFramesToAccumulate frame count is reached. Frame to frame accumulation weight remains limitted by numberOfFramesToAccumulate count. This, however, skews the result as values contribute to the end result longer than numberOfFramesToAccumulate allows.
rtx.debugView.enableFp16Accumulation	bool	False	Accumulate using fp16 precision. Default is fp32. Much of the renderer is limitted to fp16 formats so on one hand fp16 better emulates renderer's formats. On the other hand, renderer also clamps and filters the signal in many places and thus is less prone from very high values causing precision issues preventing very low values have any impact. Therefore, to minimize precision issues the default accumulation mode is set to fp32.
rtx.debugView.enableGammaCorrection	bool	False	Enables gamma correction of a debug view value.
rtx.debugView.enableInputQuantization	bool	False	Enables uniform-step input quantization on debug view input buffers. This is mostly useful for when debugging artifacts relating to quantization that may not be visible in a buffer due to higher precision formats in use. For example, the final output from tonemapping is a floating point texture in the debug view but will be quantized to 8 bit on some monitors. Using this option the quantization which will be applied to the output can be visualized in advance.
rtx.debugView.evMaxValue	int	4	The maximum EV100 debug view input value to map to the top of the visualization range when EV100 debug display is in use. Values above this value in the input will be clamped to the top of the range.
rtx.debugView.evMinValue	int	-4	The minimum EV100 debug view input value to map to the bottom of the visualization range when EV100 debug display is in use. Values below this value in the input will be clamped to the bottom of the range.
rtx.debugView.gpuPrint.enable	bool	False	Enables writing into a GPU buffer that's read by CPU when CTRL is pressed. The value is printed to console.
rtx.debugView.gpuPrint.pixelIndex	int2	2147483647, 2147483647	Pixel position to GPU print for. Requires useMousePosition to be turned off.
rtx.debugView.gpuPrint.useMousePosition	bool	True	Uses mouse position to select a pixel to GPU print for.
rtx.debugView.inverseQuantizationStepSize	float	255	The inverse of the uniform step size to quantize the debug view input to when Input Quantization is enabled. A value of 255 indicates that the input will be quantized to steps of 1/255, the same as the step size used when quantizing the range 0-1 to an 8 bit representation.
rtx.debugView.maxValue	float	1	The maximum debug view input value to map to 1 in the output when the standard debug display is in use. Values above this value in the input will be clamped to 1 in the output.
rtx.debugView.minValue	float	0	The minimum debug view input value to map to 0 in the output when the standard debug display is in use. Values below this value in the input will be clamped to 0 in the output.
rtx.debugView.numberOfFramesToAccumulate	int	1024	Number of frames to accumulate debug view's result over. This can be used for generating reference images smoothed over time. By default the accumulation stops once the limit is reached. When desired, continous accumulation can be enabled via enableContinuousAccumulation.
rtx.debugView.pseudoColorMode	int	0	Selects a mode for mapping debug value inputs to a scalar to be visualized using a colormap spectrum. Only takes effect when rtx.debugView.displayType is set to "Standard". Supported modes are: 0 = Disabled, 1 = Luminance, 2 = Red, 3 = Green, 4 = Blue, 5 = Alpha. Useful for visualizing a value's range with greater precision than a simple monochromatic color spectrum (due to interpolating across an entire spectrum of color with a roughly uniform progression).
rtx.debugView.replaceCompositeOutput	bool	False	Replaces composite output with debug view output that is generated right after composition pass. Allows for debug view output to get the post composition pipeline applied to it, such as upscaling and postprocessing actions). Note any Debug Views having data set post Composite pass require this setting to be disabled to work. When disabled Debug View output is generated close to the end of RTX pipeline (after postprocessing and upscaling).
rtx.debugView.samplerType	int	2	Sampler type for debug views that sample from a texture (applies only to a subset of debug views). Supported types are: 0 = Nearest, 1 = Normalized Nearest, 2 = Normalized Linear
rtx.debugView.showFirstGBufferHit	bool	False	Show information of the first hit surface.
rtx.defaultToAdvancedUI	bool	False
rtx.demodulate.demodulateRoughness	bool	True	Demodulate roughness to improve specular details.
rtx.demodulate.demodulateRoughnessOffset	float	0.1	Strength of roughness demodulation, lower values are stronger.
rtx.demodulate.directLightBoilingThreshold	float	5	Remove direct light sample when its luminance is higher than the average one multiplied by this threshold .
rtx.demodulate.enableDirectLightBoilingFilter	bool	True	Boiling filter removing direct light sample when its luminance is too high.
rtx.denoiseDirectAndIndirectLightingSeparately	bool	True	Denoising quality, high uses separate denoising of direct and indirect lighting for higher quality at the cost of performance.
rtx.denoiser.maxDirectHitTContribution	float	-1
rtx.denoiser.nrd.timeDeltaBetweenFrames	float	0	Frame time in milliseconds to use for denoising. Setting this to 0 will use actual frame time for a given frame. Non-zero value is primarily used for automation to ensure image output determinism.
rtx.denoiserIndirectMode	int	16
rtx.denoiserMode	int	16

rtx.di.maxHistoryLength	int	4	Maximum age of reservoirs for temporal reuse.
rtx.di.minimumConfidence	float	0.1
rtx.di.permutationSamplingNthFrame	int	0	Apply permutation sampling when (frameIdx % this == 0), 0 means off.
rtx.di.spatialSamples	int	2	The number of spatial reuse samples in converged areas.
rtx.di.stealBoundaryPixelSamplesWhenOutsideOfScreen	bool	True	Steal screen boundary samples when a hit point is outside the screen.
rtx.displacement.displacementFactor	float	1	Scaling factor for all displacement maps
rtx.displacement.enableDirectLighting	bool	True	Whether direct lighting accounts for displacement mapping
rtx.displacement.enableIndirectHit	bool	False	Whether indirect ray hits account for displacement mapping (Enabling this is expensive. Without it, non-perfect reflections of displaced objects will not show displacement.)
rtx.displacement.enableIndirectLighting	bool	True	Whether indirect lighting accounts for displacement mapping
rtx.displacement.enableNEECache	bool	True	Whether the NEE cache accounts for displacement mapping
rtx.displacement.enablePSR	bool	False	Enable PSR (perfect reflections) for materials with displacement. Rays that have been perfectly reflected off a POM surface will not collide correctly with other parts of that same surface.
rtx.displacement.enableReSTIRGI	bool	True	Whether ReSTIR GI accounts for displacement mapping
rtx.displacement.maxIterations	int	64	The max number of times the POM raymarch will iterate.
rtx.displacement.mode	int	2	What algorithm the displacement uses. RaymarchPOM: advances the ray in linear steps until the ray is below the heightfield. QuadtreePOM: Relies on special mipmaps with maximum values instead of average values. Uses the mipmap as a quadtree.
rtx.dlfg.enable	bool	True	Enables DLSS 3.0 frame generation which generates interpolated frames to increase framerate at the cost of slightly more latency.
rtx.dlssEnhancementDirectLightMaxValue	float	10	The maximum strength of direct lighting enhancement.

rtx.dlssEnhancementIndirectLightPower	float	1	The overall strength of indirect lighting enhancement.
rtx.dlssEnhancementMode	int	1	The enhancement filter type. Valid values: <Normal Difference=1, Laplacian=0>. Normal difference mode provides more normal detail at the cost of some noise. Laplacian mode is less aggressive.
rtx.dlssPreset	int	1	Combined DLSS Preset for quickly controlling Upscaling, Frame Interpolation and Latency Reduction.
rtx.drawCallRange	int2	0, 2147483647
rtx.effectLightIntensity	float	1
rtx.effectLightPlasmaBall	bool	False
rtx.effectLightRadius	float	5
rtx.emissiveBlendOverrideEmissiveIntensity	float	0.2	The emissive intensity to use when the emissive blend override is enabled. Adjust this if particles for example look overly bright globally.
rtx.emissiveIntensity	float	1	A general scale factor on all emissive intensity values globally. Generally per-material emissive intensities should be used, but this option may be useful for debugging without needing to author materials.
rtx.enableAdaptiveResolutionReplacementTextures	bool	True	A flag to enable or disable adaptive resolution replacement textures. When enabled, this mode allows replacement textures to load in only up to an adaptive minimum mip level to cut down on memory usage, but only when force high resolution replacement textures is disabled. This should generally always be enabled to ensure Remix does not starve the system of CPU or GPU memory while loading textures. Additionally, this setting must be set at startup and changing it will not take effect at runtime.
rtx.enableAlphaBlend	bool	True	Enable rendering alpha blended geometry, used for partial opacity and other blending effects on various surfaces in many games.
rtx.enableAlphaTest	bool	True	Enable rendering alpha tested geometry, used for cutout style opacity in some games.
rtx.enableAlwaysCalculateAABB	bool	False	Calculate an Axis Aligned Bounding Box for every draw call. This may improve instance tracking across frames for skinned and vertex shaded calls.
rtx.enableAsyncTextureUpload	bool	True
rtx.enableBillboardOrientationCorrection	bool	True
rtx.enableCulling	bool	True	Enable front/backface culling for opaque objects. Objects with alpha blend or alpha test are not culled.
rtx.enableCullingInSecondaryRays	bool	False	Enable front/backface culling for opaque objects. Objects with alpha blend or alpha test are not culled. Only applies in secondary rays, defaults to off. Generally helps with light bleeding from objects that aren't watertight.
rtx.enableDLSSEnhancement	bool	True	Enhances lighting details when DLSS is on.
rtx.enableDecalMaterialBlending	bool	True	A flag to enable or disable material blending on decals. This should generally always be enabled when decals are in use as this allows decals to be blended down on to the surface they sit slightly above which results in more convincing decals rendering.
rtx.enableDirectLighting	bool	True	Enables direct lighting (lighting directly from lights on to a surface) on surfaces when set to true, otherwise disables it.
rtx.enableDirectTranslucentShadows	bool	False	Include OBJECT_MASK_TRANSLUCENT into primary visibility rays.
rtx.enableEmissiveBlendEmissiveOverride	bool	True	Override typical material emissive information on draw calls with any emissive blending modes to emulate their original look more accurately.
rtx.enableEmissiveBlendModeTranslation	bool	True	Treat incoming semi/additive D3D blend modes as emissive.
rtx.enableFallbackLightShaping	bool	False	Enables light shaping on the fallback light (only used for non-Distant light types).
rtx.enableFallbackLightViewPrimaryAxis	bool	False	Enables usage of the camera's view axis as the primary axis for the fallback light's shaping (only used for non - Distant light types). Typically the shaping primary axis may be specified directly, but if desired it may be set to the camera's view axis for a "flashlight" effect.
rtx.enableFirstBounceLobeProbabilityDithering	bool	True	A flag to enable or disable screen-space probability dithering on the first indirect lobe sampled. Generally sampling a diffuse, specular or other lobe relies on a random number generated against the probability of sampling each lobe, effectively focusing more rays/paths on lobes which matter more. This can cause issues however with denoisers which do not handle sparse stochastic signals (like those from path tracing) well as they may be expecting a more "complete" signal like those used in simpler branching ray tracing setups. To help solve this issue this option uses a temporal screenspace dithering based on the probability rather than a purely random choice to determine which lobe to sample from on the first indirect bounce. This as a result helps ensure there will always be a diffuse or specular sample within the dithering pattern's area and should help the denoising resolve a more stable result.
rtx.enableFog	bool	True
rtx.enableFogColorRemap	bool	False	A flag to enable or disable remapping fixed function fox's color. Only takes effect when fog remapping in general is enabled. Enables or disables remapping functionality relating to the color parameter of fixed function fog with the exception of the multiscattering scale (as this scale can be set to 0 to disable it). This allows dynamic changes to the game's fog color to be reflected somewhat in the volumetrics system. Overrides the specified volumetric transmittance color.
rtx.enableFogMaxDistanceRemap	bool	True	A flag to enable or disable remapping fixed function fox's max distance. Only takes effect when fog remapping in general is enabled. Enables or disables remapping functionality relating to the max distance parameter of fixed function fog. This allows dynamic changes to the game's fog max distance to be reflected somewhat in the volumetrics system. Overrides the specified volumetric transmittance measurement distance.
rtx.enableFogRemap	bool	False	A flag to enable or disable fixed function fog remapping. Only takes effect when volumetrics are enabled. Typically many old games used fixed function fog for various effects and while sometimes this fog can be replaced with proper volumetrics globally, other times require some amount of dynamic behavior controlled by the game. When enabled this option allows for remapping of fixed function fog parameters from the game to volumetric parameters to accomodate this dynamic need.
rtx.enableIndirectTranslucentShadows	bool	False	Include OBJECT_MASK_TRANSLUCENT into secondary visibility rays.
rtx.enableInstanceDebuggingTools	bool	False	NOTE: This will disable temporal correllation for instances, but allow the use of instance developer debug tools
rtx.enableMultiStageTextureFactorBlending	bool	True	Support texture factor blending in stage 1~7. Currently only support 1 additional blending stage, more than 1 additional blending stages will be ignored.
rtx.enableNearPlaneOverride	bool	False	A flag to enable or disable the Camera's near plane override feature. Since the camera is not used directly for ray tracing the near plane the application uses typically does not matter, but for certain matrix-based operations (such as temporal reprojection or voxel grid projection) it is still relevant. The issue arises when geometry is ray traced that is behind where the chosen Camera's near plane is located, typically common on viewmodels especially with how they are ray traced, causing graphical artifacts and other issues. This option helps correct this issue by overriding the near plane value to else (usually smaller) to sit behind the objects in question (such as the view model). As such this option should usually be enabled on games with viewmodels. Do note that when adjusting the near plane the larger the relative magnitude gap between the near and far plane the worse the precision of matrix operations will be, so the near plane should be set as high as possible even when overriding.
rtx.enablePSRR	bool	True	A flag to enable or disable reflection PSR (Primary Surface Replacement). When enabled this feature allows higher quality mirror-like reflections in special cases by replacing the G-Buffer's surface with the reflected surface. Should usually be enabled for the sake of quality as almost all applications will utilize it in the form of glass or mirrors.
rtx.enablePSTR	bool	True	A flag to enable or disable transmission PSR (Primary Surface Replacement). When enabled this feature allows higher quality glass-like refraction in special cases by replacing the G-Buffer's surface with the refracted surface. Should usually be enabled for the sake of quality as almost all applications will utilize it in the form of glass.
rtx.enablePSTROutgoingSplitApproximation	bool	True	Enable transmission PSR on outgoing transmission events such as leaving translucent materials (rather than respecting no-split path PSR rule). Typically this results in better looking glass when enabled (at the cost of accuracy due to ignoring non-TIR inter-reflections within the glass itself).
rtx.enablePSTRSecondaryIncidentSplitApproximation	bool	True	Enable transmission PSR on secondary incident transmission events such as entering a translucent material on an already-transmitted path (rather than respecting no-split path PSR rule). Typically this results in better looking glass when enabled (at the cost accuracy due to ignoring reflections off of glass seen through glass for example).
rtx.enablePortalFadeInEffect	bool	False
rtx.enablePresentThrottle	bool	False	A flag to enable or disable present throttling, when set to true a sleep for a time specified by the throttle delay will be inserted into the DXVK presentation thread. Useful to manually reduce the framerate if the application is running too fast or to reduce GPU power usage during development to keep temperatures down. Should not be enabled in anything other than development situations.
rtx.enablePreviousTLAS	bool	True
rtx.enableRayReconstruction	bool	True	Enable ray reconstruction.
rtx.enableRaytracing	bool	True	Globally enables or disables ray tracing. When set to false the original game should render mostly as it would in DXVK typically. Some artifacts may still appear however compared to the original game either due to issues with the underlying DXVK translation or issues in Remix itself.
rtx.enableReplacementAssets	bool	True	Globally enables or disables all enhanced asset replacement (materials, meshes, lights) functionality.
rtx.enableReplacementLights	bool	True	Enables or disables enhanced light replacements. Requires replacement assets in general to be enabled to have any effect.
rtx.enableReplacementMaterials	bool	True	Enables or disables enhanced material replacements. Requires replacement assets in general to be enabled to have any effect.
rtx.enableReplacementMeshes	bool	True	Enables or disables enhanced mesh replacements. Requires replacement assets in general to be enabled to have any effect.
rtx.enableRussianRoulette	bool	True	A flag to enable or disable Russian Roulette, a rendering technique to give paths a chance of terminating randomly with each bounce based on their importance. This is usually useful to have enabled as it will ensure useless paths are terminated earlier while more important paths are allowed to accumulate more bounces. Furthermore this allows for the renderer to remain unbiased whereas a hard clamp on the number of bounces will introduce bias (though this is also done in Remix for the sake of performance). On the other hand, randomly terminating paths too aggressively may leave threads in GPU warps without work which may hurt thread occupancy when not used with a thread-reordering technique like SER.
rtx.enableSecondaryBounces	bool	True	Enables indirect lighting (lighting from diffuse/specular bounces to one or more other surfaces) on surfaces when set to true, otherwise disables it.
rtx.enableSeparateUnorderedApproximations	bool	True	Use a separate loop during resolving for surfaces which can have lighting evaluated in an approximate unordered way on each path segment (such as particles). This improves performance typically in how particles or decals are rendered and should usually always be enabled. Do note however the unordered nature of this resolving method may result in visual artifacts with large numbers of stacked particles due to difficulty in determining the intended order. Additionally, unordered approximations will only be done on the first indirect ray bounce (as particles matter less in higher bounces), and only if enabled by its corresponding setting.
rtx.enableShaderExecutionReorderingInPathtracerGbuffer	bool	False	(Note: Hard disabled in shader code) Enables Shader Execution Reordering (SER) in GBuffer Raytrace pass if SER is supported.
rtx.enableShaderExecutionReorderingInPathtracerIntegrateIndirect	bool	True	Enables Shader Execution Reordering (SER) in Integrate Indirect pass if SER is supported.
rtx.enableStochasticAlphaBlend	bool	True	Use stochastic alpha blend.
rtx.enableTransmissionApproximationInIndirectRays	bool	False	A flag to enable transmission approximations in indirect rays. Translucent objects hit by indirect rays will not alter ray direction, just change the ray throughput.
rtx.enableUnorderedEmissiveParticlesInIndirectRays	bool	False	A flag to enable or disable unordered resolve emissive particles specifically in indirect rays. Should be enabled in higher quality rendering modes as emissive particles are fairly important in reflections, but may be disabled to skip such interactions which can improve performance on lower end hardware. Note that rtx.enableUnorderedResolveInIndirectRays must first be enabled for this option to take any effect (as it will control if unordered resolve is used to begin with in indirect rays).
rtx.enableUnorderedResolveInIndirectRays	bool	True	A flag to enable or disable unordered resolve approximations in indirect rays. This allows for the presence of unordered approximations in resolving to be overridden in indirect rays and as such requires separate unordered approximations to be enabled to have any effect. This option should be enabled if objects which can be resolvered in an unordered way in indirect rays are expected for higher quality in reflections, but may come at a performance cost. Note that even with this option enabled, unordered resolve approximations are only done on the first indirect bounce for the sake of performance overall.
rtx.enableVolumetricLighting	bool	False	Enabling volumetric lighting provides higher quality ray traced physical volumetrics, disabling falls back to cheaper depth based fog. Note that disabling this option does not disable the froxel radiance cache as a whole as it is still needed for other non-volumetric lighting approximations.
rtx.enableVolumetricsInPortals	bool	True	Enables using extra frustum-aligned volumes for lighting in portals. Note that enabling this option will require 3x the memory of the typical froxel grid as well as degrade performance in some cases. This option should be enabled always in games using ray portals for proper looking volumetrics through them, but should be disabled on any game not using ray portals. Additionally, this setting must be set at startup and changing it will not take effect at runtime.
rtx.enableVsync	int	2	Controls the game's V-Sync setting. Native game's V-Sync settings are ignored.
rtx.fallbackLightAngle	float	5	The angular size in degrees to use for the fallback light (used only for Distant light types). Should only be within the range [0, 180].
rtx.fallbackLightConeAngle	float	25	The cone angle in degrees to use for the fallback light shaping (used only for non-Distant light types with shaping enabled). Should only be within the range [0, 180].

rtx.fallbackLightDirection	float3	-0.2, -1, 0.4	The direction to use for the fallback light (used only for Distant light types)
rtx.fallbackLightFocusExponent	float	2	The focus exponent to use for the fallback light shaping (used only for non-Distant light types with shaping enabled).
rtx.fallbackLightMode	int	1	The mode to determine when to create a fallback light. Never (0) never creates the light, NoLightsPresent (1) creates the fallback light only when no lights are provided to Remix, and Always (2) always creates the fallback light. Primarily a debugging feature, users should create their own lights via the Remix workflow rather than relying on this feature to provide lighting. As such, this option should be set to Never for "production" builds of Remix creations to avoid the fallback light from appearing in games unintentionally in cases where no lights exist (which is the default behavior when set to NoLightsPresent).
rtx.fallbackLightPositionOffset	float3	0, 0, 0	The position offset from the camera origin to use for the fallback light (used only for non-Distant light types).
rtx.fallbackLightPrimaryAxis	float3	0, 0, -1	The primary axis to use for the fallback light shaping (used only for non-Distant light types).
rtx.fallbackLightRadiance	float3	1.6, 1.8, 2	The radiance to use for the fallback light (used across all light types).
rtx.fallbackLightRadius	float	5	The radius to use for the fallback light (used only for Sphere light types).
rtx.fallbackLightType	int	0	The light type to use for the fallback light. Determines which other fallback light options are used.
rtx.fireflyFilteringLuminanceThreshold	float	1000	Maximum luminance threshold for the firefly filtering to clamp to.
rtx.fogColorScale	float	0.25
rtx.fogRemapColorMultiscatteringScale	float	1	A value representing the scale of the fixed function fog's color in the multiscattering approximation. This scaling factor is applied to the fixed function fog's color and becomes a multiscattering approximation in the volumetrics system. Sometimes useful but this multiscattering approximation is very basic (just a simple ambient term for now essentially) and may not look very good depending on various conditions.
rtx.fogRemapMaxDistanceMax	float	4000	A value controlling the "max distance" fixed function fog parameter's maximum remapping bound. Note that fog remapping and fog max distance remapping must be enabled for this setting to have any effect.
rtx.fogRemapMaxDistanceMin	float	100	A value controlling the "max distance" fixed function fog parameter's minimum remapping bound. Note that fog remapping and fog max distance remapping must be enabled for this setting to have any effect.
rtx.fogRemapTransmittanceMeasurementDistanceMax	float	12000	A value representing the transmittance measurement distance's maximum remapping bound. When the fixed function fog's "max distance" parameter is at or above its specified maximum the volumetric system's transmittance measurement distance will be set to this value and interpolated upwards. Note that fog remapping and fog max distance remapping must be enabled for this setting to have any effect.
rtx.fogRemapTransmittanceMeasurementDistanceMin	float	2000	A value representing the transmittance measurement distance's minimum remapping bound. When the fixed function fog's "max distance" parameter is at or below its specified minimum the volumetric system's transmittance measurement distance will be set to this value and interpolated upwards. Note that fog remapping and fog max distance remapping must be enabled for this setting to have any effect.
rtx.forceCameraJitter	bool	False
rtx.forceCutoutAlpha	float	0.5	When an object is added to the cutout textures list it will have a cutout alpha mode forced on it, using this value for the alpha test. This is meant to improve the look of some legacy mode materials using low-resolution textures and alpha blending instead of alpha cutout as this can cause blurry halos around edges due to the difficulty of handling this sort of blending in Remix. Such objects are generally better handled with actual replacement assets using fully opaque geometry replacements or alpha cutout with higher resolution textures, so this should only be relied on until proper replacements can be authored.
rtx.forceHighResolutionReplacementTextures	bool	False	A flag to enable or disable forcing high resolution replacement textures. When enabled this mode overrides all other methods of mip calculation (adaptive resolution and the minimum mipmap level) and forces it to be 0 to always load in the highest quality of textures. This generally should not be used other than for various forms of debugging or visual comparisons as this mode will ignore any constraints on CPU or GPU memory which may starve the system or Remix of memory. Additionally, this setting must be set at startup and changing it will not take effect at runtime.
rtx.freeCameraSpeed	float	200	Free camera speed [GameUnits/s].
rtx.froxelDepthSliceDistributionExponent	float	2	The exponent to use on depth values to nonlinearly distribute froxels away from the camera. Higher values bias more froxels closer to the camera with 1 being linear.
rtx.froxelDepthSlices	int	48	The z dimension of the froxel grid. Must be constant after initialization.
rtx.froxelFilterGaussianSigma	float	1.2	The sigma value of the gaussian function used to filter volumetric radiance values. Larger values cause a smoother filter to be used.

rtx.froxelKernelRadiusStabilityHistoryPower	float	2	The power to apply to the kernel radius stability history weight.
rtx.froxelMaxDistance	float	2000	The maximum distance in world units to allocate the froxel grid out to. Should be less than the distance between the camera's near and far plane, as the froxel grid will clip to the far plane otherwise.
rtx.froxelMaxKernelRadius	int	4	The maximum filtering kernel radius to use when stability is at its minimum, should be at least 1 and greater than or equal to the minimum.
rtx.froxelMaxKernelRadiusStabilityHistory	int	64	The maximum history to consider history at maximum stability for filtering.
rtx.froxelMaxReservoirSamples	int	6	The maximum number of Reservoir samples to do for each froxel cell when stability is at its minimum, should be at least 1 and greater than or equal to the minimum.
rtx.froxelMaxReservoirSamplesStabilityHistory	int	64	The maximum history to consider history at maximum stability for Reservoir samples.

rtx.graphicsPreset	int	5	Overall rendering preset, higher presets result in higher image quality, lower presets result in better performance.
rtx.gui.legacyTextureGuiShowAssignedOnly	bool	False	A setting to show only the textures in a category that are assigned to it (Unassigned textures are found in the new "Uncategorized" list at the top). Requires: 'Split Texture Category List' option to be enabled.
rtx.gui.reflexStatRangeInterpolationRate	float	0.05	A value controlling the interpolation rate applied to the Reflex stat graph ranges for smoother visualization.
rtx.gui.reflexStatRangePaddingRatio	float	0.05	A value specifying the amount of padding applied to the Reflex stat graph ranges as a ratio to the calculated range.
rtx.gui.showLegacyTextureGui	bool	False	A setting to toggle the old texture selection GUI, where each texture category is represented as its own list.
rtx.gui.textureGridThumbnailScale	float	1	A float to set the scale of thumbnails while selecting textures. This will be scaled by the default value of 120 pixels. This value must always be greater than zero.
rtx.hashCollisionDetection.enable	bool	False	Enables hash collision detection.
rtx.hideSplashMessage	bool	False	A flag to disable the splash message indicating how to use Remix from appearing when the application starts. When set to true this message will be hidden, otherwise it will be displayed on every launch.
rtx.ignoreGameDirectionalLights	bool	False	Ignores any directional lights coming from the original game (lights added via toolkit still work).
rtx.ignoreGamePointLights	bool	False	Ignores any point lights coming from the original game (lights added via toolkit still work).
rtx.ignoreGameSpotLights	bool	False	Ignores any spot lights coming from the original game (lights added via toolkit still work).
rtx.ignoreLastTextureStage	bool	False	Removes the last texture bound to a draw call, when using fixed-function pipeline. Primary textures are untouched. Might be set to true, if a game applies a lightmap as last shading step, to omit the original lightmap data.
rtx.indirectRaySpreadAngleFactor	float	0.05	A tuning factor applied to the spread angle calculated from the sampled lobe solid angle PDF. Should be 0-1. This scaled spread angle is used to widen a ray's cone angle after indirect lighting BRDF samples to essentially prefilter the effects of the BRDF lobe's spread which potentially may reduce noise from indirect rays (e.g. reflections). Prefiltering will overblur detail however compared to the ground truth of casting multiple samples especially given this calculated spread angle is a basic approximation and ray cones to begin with are a simple approximation for ray pixel footprint. As such rather than using the spread angle fully this spread angle factor allows it to be scaled down to something more narrow so that overblurring can be minimized. Similarly, setting this factor to 0 disables this cone angle widening feature.
rtx.initializer.asyncAssetLoading	bool	True
rtx.initializer.asyncShaderFinalizing	bool	True
rtx.initializer.asyncShaderPrewarming	bool	True
rtx.instanceOverrideInstanceIdx	int	-1
rtx.instanceOverrideInstanceIdxRange	int	15

rtx.instanceOverrideWorldOffset	float3	0, 0, 0
rtx.io.enabled	bool	False	When this option is enabled the assets will be loaded (and optionally decompressed on GPU) using high performance RTX IO runtime. RTX IO must be enabled for loading compressed assets, but is not necessary for working with loose uncompressed assets.
rtx.io.forceCpuDecoding	bool	False	Force CPU decoding in RTX IO.
rtx.io.memoryBudgetMB	int	256
rtx.io.useAsyncQueue	bool	True
rtx.isReflexEnabled	bool	True	Enables or disables Reflex globally. Note that this option when set to false will prevent Reflex from even attempting to initialize, unlike setting the Reflex mode to "None" which simply tells an initialized Reflex not to take effect. Additionally, this setting must be set at startup and changing it will not take effect at runtime.
rtx.isShaderExecutionReorderingSupported	bool	True	Enables support of Shader Execution Reordering (SER) if it is supported by the target HW and SW.
rtx.keepTexturesForTagging	bool	False	A flag to keep all textures in video memory, which can drastically increase VRAM consumption. Intended to assist with tagging textures that are only used for a short period of time (such as loading screens). Use only when necessary!

Should be any value larger than 0, typically within the wavelength of light, but must be less than or equal to OPAQUE_SURFACE_MATERIAL_THIN_FILM_MAX_THICKNESS ((1500.0f) nm).
rtx.legacyMaterial.useAlbedoTextureIfPresent	bool	True	A flag to determine if an "albedo" texture (a qualifying color texture) from the original application should be used if present on non-replaced "legacy" materials.
rtx.lightConversionDistantLightFixedAngle	float	0.0349	The angular size in radians of the distant light source for legacy lights converted to distant lights. Set to ~2 degrees in radians by default. Should only be within the range [0, pi].
rtx.lightConversionDistantLightFixedIntensity	float	1	The fixed intensity (in W/sr) to use for legacy lights converted to distant lights (currently directional lights will convert to distant lights).
rtx.lightConversionSphereLightFixedRadius	float	4	The fixed radius in world units to use for legacy lights converted to sphere lights (currently point and spot lights will convert to sphere lights). Use caution with large light radii as many legacy lights will be placed close to geometry and intersect it, causing suboptimal light sampling performance or other visual artifacts (lights clipping through walls, etc).
rtx.lights.debugDrawLightHashes	bool	False	Draw light hashes of all visible ob screen lights, when enableDebugMode=true.
rtx.lights.enableDebugMode	bool	False	Enables light debug visualization.

Supported enum values are 0 = None (Disabled), 1 = Spatial (Enabled, Spatial dithering only), 2 = SpatialTemporal (Enabled, Spatial and temporal dithering).
rtx.localtonemap.exposure	float	0.75	Exposure factor applied on average exposure.
rtx.localtonemap.exposurePreferenceOffset	float	0	Offset to reference luminance when calculating the weights a pixel belongs to shadow/normal/highlight areas.
rtx.localtonemap.exposurePreferenceSigma	float	4	Transition sharpness between different areas of exposure. Smaller values result in sharper transitions.

rtx.localtonemap.mip	int	3	Top mip level of tone map pyramid.
rtx.localtonemap.shadows	float	2	Shadow area strength. Higher values cause brighter shadows.

rtx.logLegacyHashReplacementMatches	bool	False
rtx.maxAccumulationFrames	int	254	The number of frames to accumulate volume lighting samples over, maximum of 254. Large values result in greater image stability at the cost of potentially more temporal lag.Should generally be set to as large a value as is viable as the froxel radiance cache is assumed to be fairly noise-free and stable which temporal accumulation helps with.
rtx.maxAnisotropySamples	float	8	The maximum number of samples to use when anisotropic filtering is enabled. The actual max anisotropy used will be the minimum between this value and the hardware's maximum. Higher values increase quality but will likely reduce performance.

rtx.minPrimsInStaticBLAS	int	1000
rtx.minReplacementTextureMipMapLevel	int	0	A parameter controlling the minimum replacement texture mipmap level to use, higher values will lower texture quality, 0 for default behavior of effectively not enforcing a minimum. This minimum will always be considered as long as force high resolution replacement textures is not enabled, meaning that with or without adaptive resolution replacement textures enabled this setting will always enforce a minimum mipmap restriction. Generally this should be changed to reduce the texture quality globally if desired to reduce CPU and GPU memory usage and typically should be controlled by some sort of texture quality setting. Additionally, this setting must be set at startup and changing it will not take effect at runtime.
rtx.minTranslucentSpecularLobeSamplingProbability	float	0.3	The minimum allowed non-zero value for translucent specular probability weights.
rtx.minTranslucentTransmissionLobeSamplingProbability	float	0.25	The minimum allowed non-zero value for translucent transmission probability weights.
rtx.nativeMipBias	float	0	Specifies a mipmapping level bias to add to all material texture filtering. Stacks with the upscaling mip bias. Mipmaps are determined based on how far away a texture is, using this can bias the desired level in a lower quality direction (positive bias), or a higher quality direction with potentially more aliasing (negative bias). Note that mipmaps are also important for good spatial caching of textures, so too far negative of a mip bias may start to significantly affect performance, therefore changing this value is not recommended
rtx.nearPlaneOverride	float	0.1	The near plane value to use for the Camera when the near plane override is enabled. Only takes effect when rtx.enableNearPlaneOverride is enabled, see that option for more information about why this is useful.
rtx.neeCache.ageCullingSpeed	float	0.02	This threshold determines culling speed of an old triangle. A triangle that is not detected for several frames will be deemed less important and culled quicker.

rtx.neeCache.minRange	float	400	The range for lowest level cells.
rtx.neeCache.resolution	float	8	Cell resolution. Higher values mean smaller cells.

rtx.opacityMicromap.buildRequests.enableParticles	bool	True	Enables Opacity Micromaps for particles.
rtx.opacityMicromap.buildRequests.filtering	bool	True	Enables filtering of Opacity Micromap requests. Filtering reduces and slows down acceptance of Opacity Micromap requests to maximize resources to requests that are more likely to be reused across instances and frames.
rtx.opacityMicromap.buildRequests.maxRequestFrameAge	int	300	Max request frame age to allow building Opacity Micromaps for. Any requests older than this are purged.
rtx.opacityMicromap.buildRequests.maxRequests	int	5000	Max number of staged unique Opacity Micromap build requests.

The higher the value, the lower latency in getting OMM data generated, but at the cost of increasing CPU load per frame on the draw call submission thread.
rtx.opacityMicromap.building.conservativeEstimation.minValidOMMTrianglesInMeshPercentage	float	0.75	Min percentage of triangles in a mesh for which valid OMM triangle arrays can be calculated. Valid OMM triangle arrays can be calculated for triangles for which the number of required texture taps is smaller or equal to "maxTexelTapsPerMicroTriangle". If the criteria is not met for a mesh, the OMMs will not be generated for the mesh.
rtx.opacityMicromap.building.costPerTexelTapPerMicroTriangleBudget	float	0.45	Approximate relative cost of doing an additional texel tap when baking micro triangles. This is used for estimating the overhead of baking micro triangles.This cost is a relative cost to doing only a single tap.

rtx.opacityMicromap.building.maxAllowedBillboardsPerInstanceToSplit	int	16	Max billboards per instance to consider for splitting (large value results in increased CPU costs on BLAS builds).
rtx.opacityMicromap.building.maxMicroTrianglesToBakeMillionPerSecond	int	300	Max Micro Triangles to bake [Million/Second]. The actual number of issued micro triangles also depends on "costPerTexelTapPerMicroTriangleBudget" option.
rtx.opacityMicromap.building.maxMicroTrianglesToBuildMillionPerSecond	int	300	Max Micro Triangles to build [Million/Second].
rtx.opacityMicromap.building.numFramesAtStartToBuildWithHighWorkload	int	0	Number of frames at start to to bake and build Opacity Micromaps with high workload multiplier. This is used for testing to decrease frame latency for Opacity Micromaps being ready.
rtx.opacityMicromap.building.splitBillboardGeometry	bool	True	Splits billboard geometry and corresponding Opacity Micromaps to quads for higher reuse. Games often batch instanced geometry that reuses same geometry and textures, such as for particles. Splitting such batches into unique subgeometries then allows higher reuse of build Opacity Micromaps.
rtx.opacityMicromap.building.subdivisionLevel	int	8	Opacity Micromap subdivision level per triangle.

rtx.opaqueMaterial.layeredWaterNormalLodBias	float	5	The LoD bias to use when sampling from the normal map on layered water for the second layer of detail. This value typically should be greater than 0 to allow for a more blurry mip to be selected as this allows for a low frequency variation of normals to be applied to the higher frequency variation from the typical normal map. Only takes effect when layered water normals are enabled (and an object is properly classified as animated water).

rtx.particleSoftnessFactor	float	0.05	Multiplier for the view distance that is used to calculate the particle blending range.
rtx.pathMaxBounces	int	4	The maximum number of indirect bounces the path will be allowed to complete. Must be < 16. Higher values result in better indirect lighting quality due to biasing the signal less, lower values result in better performance. Very high values are not recommended however as while long paths may be technically needed for unbiased rendering, in practice the contributions from higher bounces have diminishing returns.
rtx.pathMinBounces	int	1	The minimum number of indirect bounces the path must complete before Russian Roulette can be used. Must be < 16. This value is recommended to stay fairly low (1 for example) as forcing longer paths when they carry little contribution quickly becomes detrimental to performance.

rtx.presentThrottleDelay	int	16	A time in milliseconds that the DXVK presentation thread should sleep for. Requires present throttling to be enabled to take effect. Note that the application may sleep for longer than the specified time as is expected with sleep functions in general.

rtx.psrrNormalDetailThreshold	float	0	A threshold value to indicate that the denoiser's alternate disocclusion threshold should be used when normal map "detail" on a reflection PSR surface exceeds a desired amount. Normal detail is defined as 1-dot(tangent_normal, vec3(0, 0, 1)), or in other words it is 0 when no normal mapping is used, and 1 when the normal mapped normal is perpendicular to the underlying normal. This is typically used to reduce flickering artifacts resulting from reflection on surfaces like glass leveraging normal maps as often the denoiser is too aggressive with disocclusion checks frame to frame when DLSS or other camera jittering is in use.
rtx.pstrMaxBounces	int	10	The maximum number of Transmission PSR bounces to traverse. Must be 15 or less due to payload encoding. Should be set higher when refraction through many layers of glass may be needed, though more bounces may come at a higher performance cost.
rtx.pstrNormalDetailThreshold	float	0	A threshold value to indicate that the denoiser's alternate disocclusion threshold should be used when normal map "detail" on a transmission PSR surface exceeds a desired amount. Normal detail is defined as 1-dot(tangent_normal, vec3(0, 0, 1)), or in other words it is 0 when no normal mapping is used, and 1 when the normal mapped normal is perpendicular to the underlying normal. This is typically used to reduce flickering artifacts resulting from refraction on surfaces like glass leveraging normal maps as often the denoiser is too aggressive with disocclusion checks frame to frame when DLSS or other camera jittering is in use.
rtx.qualityDLSS	int	4	Adjusts internal DLSS scaling factor, trades quality for performance.
rtx.rayPortalCameraHistoryCorrection	bool	False	A flag to control if history correction on ray portal camera teleportation events is enabled or disabled. This allows for the previous camera matrix to be set to a virtual matrix to correct the large discontunity in position and view direction which happens when a camera teleports from moving through a ray portal (in games like Portal). As such this option should always be enabled in games utilizing ray portals the camera can pass through as it should fix artifacts from incorrectly calculated motion vectors or other deltas that rely on the current and previous camera matrix.
rtx.rayPortalCameraInBetweenPortalsCorrection	bool	False	A flag to contol correction when the camera is "in-between" a pair of ray portals. This is mostly relevant in applications which allow the camera to move through a ray portal (games like Portal) as often the ray portals are placed slightly off of a surface, allowing the camera to sometimes end up in this tiny gap for a frame. To correct this artifact (as it can mess up denoising and other temporal surface consistency checks due to the sudden frame of geometry in front of the camera) this option pushes the camera slightly backwards if this occurs when entering a ray portal. Similar to ray portal camera history correction this option should always be enabled in games utilizing ray portals the camera can pass through.
rtx.rayPortalCameraInBetweenPortalsCorrectionThreshold	float	0.1	The threshold to use for camera "in-between" ray portal detection in meters. When the camera is less than this distance behind the surface of a ray portal it will be pushed backwards to stay behind the ray portal. This value should stay small but be large enough to cover the gap between ray portals and the geometry behind them (if such a gap exists in the underlying application). Additionally, this setting must be set at startup and changing it will not take effect at runtime.
rtx.rayPortalEnabled	bool	False	Enables ray portal support. Note this requires portal texture hashes to be set for the ray portal geometries in rtx.rayPortalModelTextureHashes.
rtx.rayPortalModelHeightAxis	float3	0, 1, 0	The axis in object space to map the ray portal geometry's height axis to. Currently unused (as PCA is not implemented).

Currently unimplemented, kept here for future use.

rtx.restirGI.sampleStealingJitter	float	0	Jitter samples by k pixels to avoid aliasing.
rtx.restirGI.stealBoundaryPixelSamplesWhenOutsideOfScreen	bool	True	Steals ReSTIR GI samples even a hit point is outside the screen. This will further improve highly specular samples at the cost of some bias.

rtx.restirGI.validateLightingChange	bool	True	Remove samples when direct light has changed.
rtx.restirGI.validateVisibilityChange	bool	False	Remove samples when visibility has changed. This feature is automatically disabled when virtual sample is enabled.
rtx.restirGI.virtualSampleLuminanceThreshold	float	2	The last path vertex with luminance greater than 2 times of the previous accumulated radiance will get virtualized. Higher values tend to keep the first path vertex with non-zero contribution.
rtx.restirGI.virtualSampleMaxDistanceRatio	float	0	Clamp max virtual distance, measured by the proportion of distance to camera. 0 disables clamping.

rtx.risLightSampleCount	int	7	The number of lights randomly selected from the global pool to consider when selecting a light with RIS. Higher values generally increases the quality of RIS light sampling, but also has diminishing returns and higher performance cost past a point. Note that RIS is only used when RTXDI is disabled for direct lighting, or for light sampling in indirect rays, so the impact of this effect will vary.
rtx.rngSeedWithFrameIndex	bool	True	Indicates that pseudo-random number generator should be seeded with the frame number of the application every frame, otherwise seed with 0. This should generally always be enabled as without the frame index each frame will typically be identical in the random values that are produced which will result in incorrect rendering. Only meant as a debugging tool.
rtx.russianRoulette1stBounceMaxContinueProbability	float	1	The maximum probability of continuing a path when Russian Roulette is being used on the first bounce. This is similar to the usual max continuation probability for Russian Roulette, but specifically only for the first bounce.
rtx.russianRoulette1stBounceMinContinueProbability	float	0.6	The minimum probability of continuing a path when Russian Roulette is being used on the first bounce. This ensures that on the first bounce rays are not terminated too aggressively as it may be useful for some denoisers to have a contribution even if it is a relatively unimportant one rather than a missing indirect sample.
rtx.russianRouletteDiffuseContinueProbability	float	0.1	The probability of continuing a diffuse path when Russian Roulette is being used. Only apply to specular based mode.

rtx.skipObjectsWithUnknownCamera	bool	False
rtx.skyAutoDetect	int	0	Automatically tag sky draw calls using various heuristics. 0 = None 1 = CameraPosition - assume the first seen camera position is a sky camera. 2 = CameraPositionAndDepthFlags - assume the first seen camera position is a sky camera, if its draw call's depth test is disabled. If it's enabled, assume no sky camera. Note: if all draw calls are marked as sky, then assume that there's no sky camera at all.
rtx.skyBrightness	float	1
rtx.skyDrawcallIdThreshold	int	0	It's common in games to render the skybox first, and so, this value provides a simple mechanism to identify those early draw calls that are untextured (textured draw calls can still use the Sky Textures functionality.
rtx.skyForceHDR	bool	False	By default sky will be rasterized in the color format used by the game. Set the checkbox to force sky to be rasterized in HDR intermediate format. This may be important when sky textures replaced with HDR textures.

rtx.subsurface.enableTextureMaps	bool	True	Enable texture maps such as thickness map or scattering albedo map. The corresponding subsurface properties will fallback to per-material constants if this is disabled.
rtx.subsurface.enableThinOpaque	bool	True	Enable thin opaque material. The materials withthin opaque properties will fallback to normal opaque material.
rtx.subsurface.surfaceThicknessScale	float	1	Scalar of the subsurface thickness.
rtx.suppressLightKeeping	bool	False	If true, Remix doesn't keep game's original light sources for many frames. For example, if a game switches a point light off, then, in Remix, the light might still be rendered as if it's enabled: because the light would be cached (kept) for many consecutive frames. (So to solve this, set this option to True).
rtx.taauPreset	int	1	Adjusts TAA-U scaling factor, trades quality for performance.
rtx.temporalAA.colorClampingFactor	float	1	A scalar factor to apply to the standard deviation of the neighborhood of pixels in the color signal used for clamping. Should be in the range 0-infinity. This value essentially represents how many standard deviations of tolerance from the current frame's colors around each pixel pixel the temporally accumulated color signal may have. Higher values will cause more ghosting whereas lower values may reduce ghosting but will impact image quality (less ability to upscale effectively) and reduce stability (more jittering).
rtx.temporalAA.maximumRadiance	float	10000	The maximum value to use in TAA-U's perceptual quantizer color transformation, measured in cd/m^2. The typical value used for the PQ transformation is 10,000 and usually shouldn't be changed.
rtx.temporalAA.newFrameWeight	float	0.1	The maximum amount of the current frame to use as part of the temporal anti-aliasing process. Must be in the range 0-1. Values closer to 0 will result in better image stability (less jittering) and less aliasing, values closer to 1 will result in more responsive results (less ghosting).

rtx.terrainBaker.debugDisableBaking	bool	False	Force disables rebaking every frame. Used for debugging only.
rtx.terrainBaker.debugDisableBinding	bool	False	Force disables binding of the baked terrain texture to the terrain meshes. Used for debugging only.
rtx.terrainBaker.enableBaking	bool	True	[Experimental] Enables runtime baking of blended terrains from top down (i.e. in an opposite direction of "rtx.zUp"). It bakes multiple blended albedo terrain textures into a single texture sampled during ray tracing. The system requires "Terrain Textures" to contain hashes of the terrain textures to apply. Only use this system if the game renders terrain surfaces with multiple blended surfaces on top of each other (i.e. sand mixed with dirt, grass, snow, etc.). Requirement: the baked terrain surfaces must not be placed vertically in the game world. Horizontal surfaces will have the best image quality. Requires "rtx.zUp" to be set properly.
rtx.terrainBaker.material.bakeReplacementMaterials	bool	True	Enables baking of replacement materials when they are present.
rtx.terrainBaker.material.bakeSecondaryPBRTextures	bool	True	Enables baking of secondary textures in replacement materials when they are present. Secondary textures are all PBR textures except for albedoOpacity. So that includes normal, roughness, etc.
rtx.terrainBaker.material.maxResolutionToUseForReplacementMaterials	int	8192	Max resolution to use for preprocessing and baking of input replacement material textures other than color opacity which is used as is. Applies only to a case when a preprocessing compute shader is used to support baking of secondary PBR materials. Replacement materials need to be preprocessed prior to baking them and limitting the max resolution allows to balance the quality vs performance cost.
rtx.terrainBaker.material.properties.displaceInFactor	float	1	The max depth the baked terrain can support will be larger than the max depth of any incoming draw call, which results in a loss of detail. When this is too low, the displacement will lack detail. When it is too high, the lowest parts of the POM will flatten out.
rtx.terrainBaker.material.properties.emissiveColorConstant	float3	0, 0, 0	Emissive color constant. Should be a color in sRGB colorspace with gamma encoding.
rtx.terrainBaker.material.properties.emissiveIntensity	float	0	Emissive intensity.
rtx.terrainBaker.material.properties.enableEmission	bool	False	A flag to determine if emission is enabled.
rtx.terrainBaker.material.properties.metallicConstant	float	0.1	Metallic constant. Valid range is <0, 1>.
rtx.terrainBaker.material.properties.roughnessAnisotropy	float	0	Roughness anisotropy. Valid range is <-1, 1>, where 0 is isotropic.
rtx.terrainBaker.material.properties.roughnessConstant	float	0.7	Perceptual roughness constant. Valid range is <0, 1>.
rtx.terrainBaker.material.replacementSupportInPS	bool	True	Enables reading of secondary PBR replacement textures in pixel shaders when supported. Current support is limitted to fixed function pipelines and programmable shaders with Shader Model 1.0. When set to false or unsupported, an extra compute shader is used to preproces the secondary textures to make them compatible at an expense of performance and quality instead. Requires "rtx.terrainBaker.material.replacementSupportInPS_fixedFunction = True" to apply for draw calls with fixed function graphics pipeline. Requires "rtx.terrainBaker.material.replacementSupportInPS_programmableShaders = True" to apply for draw calls with programmable graphics pipeline.
rtx.terrainBaker.material.replacementSupportInPS_fixedFunction	bool	True	Enables reading of secondary PBR replacement textures in pixel shaders for games with fixed function graphics pipelines. When set to false, an extra compute shader is used to preproces the secondary textures to make them compatible at an expense of performance and quality instead. This parameter must be set at launch to apply.
rtx.terrainBaker.material.replacementSupportInPS_programmableShaders	bool	True	[Experimental] Enables reading of secondary PBR replacement textures in pixel shaders for games with programmable graphics pipelines."When set to false, an extra compute shader is used to preproces the secondary textures to make them compatible at an expense of performance and quality instead. This parameter must be set at launch to apply. The current support for this is limitted to draw calls with programmable shaders with Shader Model 1.0 only. Draw calls with Shader Model 2.0+ will use the preprocessing compute pass.
rtx.texturemanager.budgetPercentageOfAvailableVram	int	50	The percentage of available VRAM we should use for material textures. If material textures are required beyond this budget, then those textures will be loaded at lower quality. Important note, it's impossible to perfectly match the budget while maintaining reasonable quality levels, so use this as more of a guideline. If the replacements assets are simply too large for the target GPUs available vid mem, we may end up going overbudget regularly. Defaults to 50% of the available VRAM.
rtx.texturemanager.showProgress	bool	False	Show texture loading progress in the HUD.
rtx.timeDeltaBetweenFrames	float	0	Frame time delta in milliseconds to use for rendering. Setting this to 0 will use actual frame time delta for a given frame. Non-zero value allows the actual time delta to be overridden and is primarily used for automation to ensure determinism run to run without variance due to frame time fluctuations.
rtx.tonemap.colorBalance	float3	1, 1, 1	The color tint to apply after tonemapping when color grading is enabled for the tonemapper (rtx.tonemap.colorGradingEnabled). Values should be in the range [0, 1].
rtx.tonemap.colorGradingEnabled	bool	False	A flag to enable or disable color grading after the global tonemapper's tonemapping pass, but before gamma correction and dithering (if enabled).
rtx.tonemap.contrast	float	1	The contrast adjustment to apply after tonemapping when color grading is enabled for the tonemapper (rtx.tonemap.colorGradingEnabled). Values should be in the range [0, 1].
rtx.tonemap.curveShift	float	0	Range [0, inf). Amount by which to shift the tone curve up or down. Nonzero values will cause additional clipping.
rtx.tonemap.ditherMode	int	2	Tonemap dither mode selection, dithering allows for reduction of banding artifacts in the final rendered output from quantization using a small amount of monochromatic noise. Impact typically most visible in darker regions with smooth lighting gradients. Enabling dithering will make the rendered image slightly noisier, though usually dither noise is fairly imperceptible in most cases without looking closely. Generally dithered results will also look better than the alternative of banding artifacts due to increasing perceptual precision of the signal. Note that temporal dithering may increase perceptual precision further but may also introduce more noticeable noise in the final output in some cases due to the noise pattern changing every frame unlike a purely spatial approach. Supported enum values are 0 = None (Disabled), 1 = Spatial (Enabled, Spatial dithering only), 2 = SpatialTemporal (Enabled, Spatial and temporal dithering). Generally enabling dithering is recommended, but disabling it may be useful in some niche cases for improving compression ratios in images or videos at the cost of quality (as noise while it may not be very visible may be more difficult to compress), or for capturing "raw" post-tonemapped data from the renderer.
rtx.tonemap.dynamicRange	float	15	Range [0, inf). Without further adjustments, the tone curve will try to fit the entire luminance of the scene into the range [-dynamicRange, 0] in linear photographic stops. Higher values adjust for ambient monitor lighting; perfect conditions -> 17.587 stops.
rtx.tonemap.exposureBias	float	0	The exposure value to use for the global tonemapper when auto exposure is disabled, or a bias multiplier on top of the auto exposure's calculated exposure value.
rtx.tonemap.finalizeWithACES	bool	False	A flag to enable applying a final pass of ACES tonemapping to the tonemapped result.
rtx.tonemap.maxExposureIncrease	float	5	Range [0, inf). Forces the tone curve to not increase luminance values at any point more than this value.
rtx.tonemap.saturation	float	1	The saturation adjustment to apply after tonemapping when color grading is enabled for the tonemapper (rtx.tonemap.colorGradingEnabled). Values should be in the range [0, 1].
rtx.tonemap.shadowContrast	float	0	Range [0, inf). Additional gamma power to apply to the tone of the tone curve below shadowContrastEnd.
rtx.tonemap.shadowContrastEnd	float	0	Range (-inf, 0]. High endpoint for the shadow contrast effect in linear stops; values above this are unaffected.
rtx.tonemap.shadowMinSlope	float	0	Range [0, inf). Forces the tone curve below a linear value of 0.18 to have at least this slope, making the tone darker.
rtx.tonemap.toneCurveMaxStops	float	8	High endpoint of the tone curve (in log2(linear)).
rtx.tonemap.toneCurveMinStops	float	-24	Low endpoint of the tone curve (in log2(linear)).
rtx.tonemap.tonemappingEnabled	bool	True	A flag to enable or disable the local tonemapper. Note this flag will only take effect when the global tonemapper is set to be used (as opposed to another option such as the local tonemapper).
rtx.tonemap.tuningMode	bool	False	A flag to enable a debug visualization to tune the tonemapping exposure curve with, as well as exposing parameters for tuning the tonemapping in the UI.
rtx.tonemappingMode	int	1	The tonemapping type to use, 0 for Global, 1 for Local (Default). Global tonemapping tonemaps the image with respect to global parameters, usually based on statistics about the rendered image as a whole. Local tonemapping on the other hand uses more spatially-local parameters determined by regions of the rendered image rather than the whole image. Local tonemapping can result in better preservation of highlights and shadows in scenes with high amounts of dynamic range whereas global tonemapping may have to comprimise between over or underexposure.
rtx.trackParticleObjects	bool	True	Track last frame's corresponding particle object.
rtx.translucentDecalAlbedoFactor	float	10	A global scale factor applied to the albedo of decals that are applied to a translucent base material, to make the decals more visible. This is generally needed as albedo values for decals may be fairly low when dealing with opaque surfaces, but the translucent diffuse layer requires a fairly high albedo value to result in an expected look. The need for this option could be avoided by simply authoring decals applied to translucent materials with a higher albedo to begin with, but sometimes applications may share decals between different material types.
rtx.translucentMaterial.enableDiffuseLayerOverride	bool	False	A flag to force the diffuse layer on the translucent material to be enabled. Should only be used for debugging or development.
rtx.translucentMaterial.normalIntensity	float	1	An arbitrary strength scale factor to apply when decoding normals in the translucent material. Should only be used for debugging or development.
rtx.translucentMaterial.transmittanceColorBias	float	0	A bias factor to add to all transmittance color values in the opaque material. Should only be used for debugging or development.
rtx.translucentMaterial.transmittanceColorScale	float	1	A scale factor to apply to all transmittance color values in the translucent material. Should only be used for debugging or development.
rtx.translucentSpecularLobeSamplingProbabilityZeroThreshold	float	0.01	The threshold for which to zero translucent specular probability weight values.
rtx.translucentTransmissionLobeSamplingProbabilityZeroThreshold	float	0.01	The threshold for which to zero translucent transmission probability weight values.
rtx.uniqueObjectDistance	float	300	The distance (in game units) that an object can move in a single frame before it is no longer considered the same object. If this is too low, fast moving objects may flicker and have bad lighting. If it's too high, repeated objects may flicker. This does not account for sceneScale.
rtx.upscalerType	int	1	Upscaling boosts performance with varying degrees of image quality tradeoff depending on the type of upscaler and the quality mode/preset.
rtx.upscalingMipBias	float	0	Specifies a mipmapping level bias to add to all material texture filtering when upscaling (such as DLSS) is used. Mipmaps are determined based on how far away a texture is, using this can bias the desired level in a lower quality direction (positive bias), or a higher quality direction with potentially more aliasing (negative bias). Note that mipmaps are also important for good spatial caching of textures, so too far negative of a mip bias may start to significantly affect performance, therefore changing this value is not recommended
rtx.useAnisotropicFiltering	bool	True	A flag to indicate if anisotropic filtering should be used on material textures, otherwise typical trilinear filtering will be used. This should generally be enabled as anisotropic filtering allows for less blurring on textures at grazing angles than typical trilinear filtering with only usually minor performance impact (depending on the max anisotropy samples).
rtx.useBuffersDirectly	bool	True	When enabled Remix will use the incoming vertex buffers directly where possible instead of copying data. Note: setting the d3d9.allowDiscard to False will disable this option.
rtx.useDenoiser	bool	True	Enables usage of denoiser(s) when set to true, otherwise disables denoising when set to false. Denoising is important for filtering the raw noisy ray traced signal into a smoother and more stable result at the cost of some potential spatial/temporal artifacts (ghosting, boiling, blurring, etc). Generally should remain enabled except when debugging behavior which requires investigating the output directly, or diagnosing denoising-related issues.
rtx.useDenoiserReferenceMode	bool	False	Enables reference "denoiser" (~ accumulation mode) when set to true, otherwise uses a standard denoiser. The reference denoiser accumulates frames over time to generate a reference multi-sample per pixel contribution which should converge slowly to the ideal result the renderer is working towards. It is useful for analyzing quality differences in various denoising methods, post-processing filters, or for more accurately comparing subtle effects of potentially biased rendering techniques which may be hard to see through noise and filtering. It is also useful for higher quality artistic renders of a scene beyond what is possible in real-time.
rtx.useHighlightLegacyMode	bool	False
rtx.useHighlightUnsafeAnchorMode	bool	False
rtx.useHighlightUnsafeReplacementMode	bool	False
rtx.useIntersectionBillboardsOnPrimaryRays	bool	False
rtx.useLiveShaderEditMode	bool	False	When set to true shaders will be automatically recompiled when any shader file is updated (saved for instance) in addition to the usual manual recompilation trigger.
rtx.useObsoleteHashOnTextureUpload	bool	False	Whether or not to use slower XXH64 hash on texture upload. New projects should not enable this option as this solely exists for compatibility with older hashing schemes.
rtx.usePartialDdsLoader	bool	True	A flag controlling if the partial DDS loader should be used, true to enable, false to disable and use GLI instead. Generally this should be always enabled as it allows for simple parsing of DDS header information without loading the entire texture into memory like GLI does to retrieve similar information. Should only be set to false for debugging purposes if the partial DDS loader's logic is suspected to be incorrect to compare against GLI's implementation.
rtx.usePostFilter	bool	True	Uses post filter to remove fireflies in the denoised result.
rtx.useRTXDI	bool	True	A flag indicating if RTXDI should be used, true enables RTXDI, false disables it and falls back on simpler light sampling methods. RTXDI provides improved direct light sampling quality over traditional methods and should generally be enabled for improved direct lighting quality at the cost of some performance.
rtx.useRayPortalVirtualInstanceMatching	bool	True
rtx.useReSTIRGI	bool	True	A flag indicating if ReSTIR GI should be used, true enables ReSTIR GI, false disables it and relies on typical GI sampling. ReSTIR GI provides improved indirect path sampling over typical importance sampling and should usually be enabled for better indirect diffuse and specular GI quality at the cost of some performance.
rtx.useVertexCapture	bool	True	When enabled, injects code into the original vertex shader to capture final shaded vertex positions. Is useful for games using simple vertex shaders, that still also set the fixed function transform matrices.
rtx.useVertexCapturedNormals	bool	True	When enabled, vertex normals are read from the input assembler and used in raytracing. This doesn't always work as normals can be in any coordinate space, but can help sometimes.
rtx.useVirtualShadingNormalsForDenoising	bool	True	A flag to enable or disable the usage of virtual shading normals for denoising passes. This is primairly important for anything that modifies the direction of a primary ray, so mainly PSR and ray portals as both of these will view a surface from an angle different from the "virtual" viewing direction perceived by the camera. This can cause some issues with denoising due to the normals not matching the expected perception of what the normals should be, for example normals facing away from the camera direction due to being viewed from a different angle via refraction or portal teleportation. To correct this, virtual normals are calculcated such that they always are oriented relative to the primary camera ray as if its direction was never altered, matching the virtual perception of the surface from the camera's point of view. As an aside, virtual normals themselves can cause issues with denoising due to the normals suddenly changing from virtual to "real" normals upon traveling through a portal, causing surface consistency failures in the denoiser, but this is accounted for via a special transform given to the denoiser on camera ray portal teleportation events. As such, this option should generally always be enabled when rendering with ray portals in the scene to have good denoising quality.
rtx.useWhiteMaterialMode	bool	False	Override all objects' materials by white material
rtx.useWorldMatricesForShaders	bool	True	When enabled, Remix will utilize the world matrices being passed from the game via D3D9 fixed function API, even when running with shaders. Sometimes games pass these matrices and they are useful, however for some games they are very unreliable, and should be filtered out. If you're seeing precision related issues with shader vertex capture, try disabling this setting.
rtx.validateCPUIndexData	bool	False
rtx.vertexColorStrength	float	0.6	A scalar to apply to how strong vertex color influence should be on materials. A value of 1 indicates that it should be fully considered (though do note the texture operation and relevant parameters still control how much it should be blended with the actual albedo color), a value of 0 indicates that it should be fully ignored.
rtx.viewDistance.distanceFadeMax	float	500	The view distance based on the result of the view distance function to end view distance noise fading at (and effectively draw nothing past this point), only used for the Coherent Noise view distance mode.
rtx.viewDistance.distanceFadeMin	float	400	The view distance based on the result of the view distance function to start view distance noise fading at, only used for the Coherent Noise view distance mode.
rtx.viewDistance.distanceFunction	int	0	The view distance function, Euclidean is a simple distance from the camera, whereas Planar Euclidean will ignore distance across the world's "up" direction.
rtx.viewDistance.distanceMode	int	0	The view distance mode, None disables view distance, Hard Cutoff will cut off geometry past a point, and Coherent Noise will feather geometry out using a stable worldspace noise pattern (experimental).
rtx.viewDistance.distanceThreshold	float	500	The view distance to draw out to based on the result of the view distance function, only used for the Hard Cutoff view distance mode.
rtx.viewDistance.noiseScale	float	3	The scale per meter value applied to ther world space position fed into the noise generation function for generating the fade in Coherent Noise view distance mode.
rtx.viewModel.enable	bool	False	If true, try to resolve view models (e.g. first-person weapons). World geometry doesn't have shadows / reflections / etc from the view models.
rtx.viewModel.enableVirtualInstances	bool	True	If true, virtual instances are created to render the view models behind a portal.
rtx.viewModel.maxZThreshold	float	0	If a draw call's viewport has max depth less than or equal to this threshold, then assume that it's a view model.
rtx.viewModel.perspectiveCorrection	bool	True	If true, apply correction to view models (e.g. different FOV is used for view models).
rtx.viewModel.rangeMeters	float	1	[meters] Max distance at which to find a portal for view model virtual instances. If rtx.viewModel.separateRays is true, this is also max length of view model rays.
rtx.viewModel.scale	float	1	Scale for view models. Minimize to prevent clipping.
rtx.volumetricAnisotropy	float	0	The anisotropy of the scattering phase function (-1 being backscattering, 0 being isotropic, 1 being forward scattering).
rtx.volumetricClampedReprojectionConfidencePenalty	float	0.5	The penalty from [0, 1] to apply to the sample count of temporally reprojected reservoirs when reprojection is clamped to the fustrum (indicating lower quality reprojection).
rtx.volumetricEnableInitialVisibility	bool	True	Determines whether to trace a visibility ray for Reservoir samples. Results in slightly higher quality froxel grid light samples at the cost of a ray per froxel cell each frame and should generally be enabled.
rtx.volumetricEnableTemporalResampling	bool	True	Indicates if temporal resampling should be used for volume integration. Temporal resampling allows for reuse of temporal information when picking froxel grid light samples similar to how ReSTIR works, providing higher quality light samples. This should generally be enabled but currently due to the lack of temporal bias correction this option will slightly bias the lighting result.
rtx.volumetricInitialRISSampleCount	int	8	The number of RIS samples to select from the global pool of lights when constructing a Reservoir sample. Higher values generally increases the quality of the selected light sample, though similar to the general RIS light sample count has diminishing returns.
rtx.volumetricSingleScatteringAlbedo	float3	0.9, 0.9, 0.9	The single scattering albedo (otherwise known as the particle albedo) representing the ratio of scattering to absorption. While color-like in many ways this value is assumed to be more of a mathematical albedo (unlike material albedo which is treated more as a color), and is therefore treated as linearly encoded data (not gamma).
rtx.volumetricTemporalReuseMaxSampleCount	int	200	The number of samples to clamp temporal reservoirs to, should usually be around the value: desired_max_history_frames * average_reservoir_samples.
rtx.volumetricTransmittanceColor	float3	0.953237, 0.92879, 0.903545	The color to use for calculating transmittance measured at a specific distance. Note that this color is assumed to be in sRGB space and gamma encoded as it will be converted to linear for use in volumetrics.
rtx.volumetricTransmittanceMeasurementDistance	float	10000	The distance the specified transmittance color was measured at. Lower distances indicate a denser medium.
rtx.worldSpaceUiBackgroundOffset	float	-0.01	Distance along normal to offset objects rendered as worldspace UI, specifically for the background of screens.
rtx.zUp	bool	False	Indicates that the Z axis is the "upward" axis in the world when true, otherwise the Y axis when false.

Complex Types

RTX Option	Type	Default Value	Description
rtx.animatedWaterTextures	hash set		Textures on draw calls to be treated as "animated water". Objects with this flag applied will animate their normals to fake a basic water effect based on the layered water material parameters, and only when rtx.opaqueMaterial.layeredWaterNormalEnable is set to true. Should typically be used on static water planes that the original application may have relied on shaders to animate water on.
rtx.antiCulling.antiCullingTextures	hash set		Textures that are forced to extend life length when anti-culling is enabled. Some games use different culling methods we can't fully match, use this option to manually add textures to force extend their life when anti-culling fails.
rtx.baseGameModPathRegex	string		Regex used to redirect RTX Remix Runtime to another path for replacements and rtx.conf.
rtx.baseGameModRegex	string		Regex used to determine if the base game is running a mod, like a sourcemod.
rtx.beamTextures	hash set		Textures on draw calls that are already particles or emissively blended and have beam-like geometry. Typically objects marked as particles or objects using emissive blending will be rendered with a special method which allows re-orientation of the billboard geometry assumed to make up the draw call in indirect rays (reflections for example). This method works fine for typical particles, but some (e.g. a laser beam) may not be well-represented with the typical billboard assumption of simply needing to rotate around its centroid to face the view direction. To handle such cases a different beam mode is used to treat objects as more of a cylindrical beam and re-orient around its main spanning axis, allowing for better rendering of these beam-like effect objects.
rtx.cameraSequence.filePath	string		File path.
rtx.captureInstanceStageName	string	capture_{timestamp}.usd	Name of the 'instance' stage (see: 'rtx.captureInstances')
rtx.captureTimestampReplacement	string	{timestamp}	String that can be used for auto-replacing current time stamp in instance stage name
rtx.decalTextures	hash set		Textures on draw calls used for static geometric decals or decals with complex topology. These materials will be blended over the materials underneath them when decal material blending is enabled. A small configurable offset is applied to each flat/co-planar part of these decals to prevent coplanar geometric cases (which poses problems for ray tracing).
rtx.dynamicDecalTextures	hash set		Warning: This option is deprecated, please use rtx.decalTextures instead. Textures on draw calls used for dynamically spawned geometric decals, such as bullet holes. These materials will be blended over the materials underneath them when decal material blending is enabled. A small configurable offset is applied to each quad part of these decals to prevent coplanar geometric cases (which poses problems for ray tracing).
rtx.geometryAssetHashRuleString	string	positions,indices,geometrydescriptor	Defines which hashes we need to include when sampling from replacements and doing USD capture.
rtx.geometryGenerationHashRuleString	string	positions,indices,texcoords,geometrydescriptor,vertexlayout,vertexshader	Defines which asset hashes we need to generate via the geometry processing engine.
rtx.hideInstanceTextures	hash set		Textures on draw calls that should be hidden from rendering, but not totally ignored. This is similar to rtx.ignoreTextures but instead of completely ignoring such draw calls they are only hidden from rendering, allowing for the hidden objects to still appear in captures. As such, this is mostly only a development tool to hide objects during development until they are properly replaced, otherwise the objects should be ignored with rtx.ignoreTextures instead for better performance.
rtx.ignoreBakedLightingTextures	hash set		Textures for which to ignore two types of baked lighting, Texture Factors and Vertex Color. Texture Factor disablement: Using this feature on selected textures will eliminate the texture factors. For instance, if a game bakes lighting information into the Texture Factor for particular textures, applying this option will remove them. This becomes useful when unexpected results occur due to the Texture Factor. Consider an example where the original texture contains red tints baked into the Texture Factor. If a user replaces the texture, it will blend with the red tints, resulting in an undesirable reddish outcome. In such cases, users can employ this option to eliminate the unwanted tints from their replacement textures. Similarly, users can tag textures if shadows are baked into the Texture Factor, causing the replacing texture to appear darker than anticipated. Vertex Color disablement: Using this feature on selected textures will eliminate the vertex colors. Note, enabling this setting will automatically disable multiple-stage texture factor blendings for the selected textures. Only use this option when necessary, as the Texture Factor and Vertex Color can be used for simulating various texture effects, tagging a texture with this option will unexpectedly eliminate these effects.
rtx.ignoreLights	hash set		Lights that should be ignored. Any matching light will be skipped and not added to be ray traced.
rtx.ignoreTextures	hash set		Textures on draw calls that should be ignored. Any draw call using an ignore texture will be skipped and not ray traced, useful for removing undesirable rasterized effects or geometry not suitable for ray tracing.
rtx.lightConverter	hash set
rtx.lightmapTextures	hash set		Textures used for lightmapping (baked static lighting on surfaces) in older games. These textures will be ignored when attempting to determine the desired textures from a draw to use for ray tracing.
rtx.nonOffsetDecalTextures	hash set		Warning: This option is deprecated, please use rtx.decalTextures instead. Textures on draw calls used for geometric decals with arbitrary topology that are already offset from the base geometry. These materials will be blended over the materials underneath them when decal material blending is enabled. Unlike typical decals however these decals have no offset applied to them due assuming the offset is already being done by whatever is passing data to Remix.
rtx.opacityMicromapIgnoreTextures	hash set		Textures to ignore when generating Opacity Micromaps. This generally does not have to be set and is only useful for black listing problematic cases for Opacity Micromap usage.
rtx.particleTextures	hash set		Textures on draw calls that should be treated as particles. When objects are marked as particles more approximate rendering methods are leveraged allowing for more effecient and typically better looking particle rendering. Generally any billboard-like blended particle objects in the original application should be classified this way.
rtx.playerModelBodyTextures	hash set
rtx.playerModelTextures	hash set
rtx.postfx.motionBlurMaskOutTextures	hash set		Disable motion blur for meshes with specific texture.
rtx.rayPortalModelTextureHashes	hash vector		Texture hashes identifying ray portals. Allowed number of hashes: {0, 2}.
rtx.singleOffsetDecalTextures	hash set		Warning: This option is deprecated, please use rtx.decalTextures instead. Textures on draw calls used for geometric decals that don't inter-overlap for a given texture hash. Textures must be tagged as "Decal Texture" or "Dynamic Decal Texture" to apply. Applies a single shared offset to all the batched decal geometry rendered in a given draw call, rather than increasing offset per decal within the batch (i.e. a quad in case of "Dynamic Decal Texture"). Note, the offset adds to the global offset among all decals drawn with different draw calls. The decal textures tagged this way must not inter-overlap within a batch / single draw call since the same offset is applied to all of them. Applying a single offset is useful for stabilizing decal offsets when a game dynamically batches decals together. In addition, it makes the global decal offset index grow slower and thus it minimizes a chance of hitting the "rtx.decals.maxOffsetIndex limit".
rtx.skyBoxGeometries	hash set		Geometries from draw calls used for the sky or are otherwise intended to be very far away from the camera at all times (no parallax). Any draw calls using a geometry hash in this list will be treated as sky and rendered as such in a manner different from typical geometry. The geometry hash being used for sky detection is based off of the asset hash rule, see: "rtx.geometryAssetHashRuleString".
rtx.skyBoxTextures	hash set		Textures on draw calls used for the sky or are otherwise intended to be very far away from the camera at all times (no parallax). Any draw calls using a texture in this list will be treated as sky and rendered as such in a manner different from typical geometry.
rtx.sourceRootPath	string		A path pointing at the root folder of the project, used to override the path to the root of the project generated at build-time (as this path is only valid for the machine the project was originally compiled on). Used primarily for locating shader source files for runtime shader recompilation.
rtx.terrainTextures	hash set		Albedo textures that are baked blended together to form a unified terrain texture used during ray tracing. Put albedo textures into this category if the game renders terrain as a blend of multiple textures.
rtx.uiTextures	hash set		Textures on draw calls that should be treated as screenspace UI elements. All exclusively UI-related textures should be classified this way and doing so allows the UI to be rasterized on top of the ray traced scene like usual. Note that currently the first UI texture encountered triggers RTX injection (though this may change in the future as this does cause issues with games that draw UI mid-frame).
rtx.welcomeMessage	string		Display a message to the user on startup, leave empty if no message is to be displayed.
rtx.worldSpaceUiBackgroundTextures	hash set		Hack/workaround option for dynamic world space UI textures with a coplanar background. Apply to backgrounds if the foreground material is a dynamic world texture rendered in UI that is unpredictable and rapidly changing. This offsets the background texture backwards.
rtx.worldSpaceUiTextures	hash set		Textures on draw calls that should be treated as worldspace UI elements. Unlike typical UI textures this option is useful for improved rendering of UI elements which appear as part of the scene (moving around in 3D space rather than as a screenspace element).
