remix-0.4.0

190fb82

remix-0.4.0

Notable changes since Remix 0.3.0:

DXVK:

Fixed several capture-related issues.
Fixed geometry corruption in shader-based games.
Added texture sampler state capture support.
Resolved an issue with sampler state overriding in the mod.
Fixed a race condition causing crashes when loading scenes with no textures in HdRemix.
Code improvements and bug fixes for Opacity Micromap.
Fixed draw call corruption in cases of high CPU load.
Simplified decal handling for better performance.
Several stability fixes for DLSS-FG
Removed the warning about assets not being production-ready.
Fixed a bug preventing toolkit from adding replacements during instance capture.
Moved doublesided flag to instance info for better handling.
Added support for dome lights via the Remix SDK API.
Prevented division by zero by clamping transmittance color.
Added gamma correction to debug view for improved visualization.
Improvements for anti-culling system for in-game lights
Stability and performance improvements for terrain baking
Improved and extended Parallax Occlusion Mapping support
Updates and fixes for subsurface scattering support on thin surfaces

Bridge:

Fixed command retry behavior in both the bridge server and client, which could have led to the game hanging forever.
Also fixed a failure case where the client improperly gave up on trying to avoid a data queue override, which could lead to game crashes.
Improved server behavior where now the DataQueue will only wait briefly instead of waiting for the server to catch up completely, which could cause game hangs or crashes.
Fixed a corner case where the writer will overwrite data the reader hasn't read yet when the reader is exactly one circular buffer behind the writer. This could cause buffer corruption, leading to subsequent game crashes.
Fixed issue with GetRenderTargetData() API response handling to make it safe for multithreading by using the same mechanism applied to other APIs to ensure thread safety.

remix-0.3.0

Enhancements and Optimizations:
- DLSS 3.0 (Frame Generation) support comes to the RTX Remix runtime, with better stability and frame pacing
- Collapsed Capture UI when capturing is disabled:
  - Prevents UI below the capture section from moving when toggling enhancements.
- Optimized Terrain Baking of Secondary PBR Textures via Shader Injection:
  - Introduces changes related to texture baking and shader support.
- Included USD Folder in GitHub Artifacts
- Refactor Instance Categories for Toolkit Support:
  - Refactors instance categories and texture tagging for toolkit support.
- SER and Graphics Pipeline:
  - Implemented a coherence hint, boosting indirect pass performance by 2-8% in scenes with particles.
- Graphics Pipeline Optimization:
  - Reworked ThreadPool for ~30% CPU time improvement on both CS and main sides
  - Used a separate command list to process skinning dispatches, resulting in improved performance
  - Combined hit shaders used for TraceRay dispatches into a single shader for optimization
  - Updated legacy state handling in the D3D9 layer
- RTXIO Integration:
  - Added multi-package support to RTXIO.
  - Modified USD mod to work without loose image files.
  - Cleaned up object references in RTXIO.
- Material Texture Budgeting:
  - Implemented a budget for material textures. As users start to run out of VRAM, Remix will automatically reduce texture resolution to keep users within their budget.
  - Moved texture caching to the texture manager.
  - Implemented logic for dynamic mip dropping when the budget is full.
Bug Fixes and Stability:
- Fixed Anti-Culling Bugs:
  - Resolves corner cases in SAT and duplication issues in anti-culling.
  - Modifies default settings slightly.
- Fixed a crash when dealing with replacements relating to skies in some scenarios
- Fixed heap corruption crashes in debug builds
- Updated USD to the latest version, resolving compatibility problems.
Texture Handling Fixes:
- Fixed texture transform usage in the Opacity Micromap baker.
- Fixed incorrect Scratch Buffer alignment.
- Fully evicted cached memory after loading images.
General Bug Fixes:
- Fixed recursive_copy.bat for paths with spaces.
- Fixed file naming format to follow DXVK and RTX shader format.
Performance and Resource Management:
- Enhanced resource management by releasing terrain baker resources when terrain baking is not in use
- Texture Transform Tweaks:
  - Optimized texture transform storage in surface structures, reducing footprint.
  - Added warnings for unsupported texture transforms in Remix.
Shader and Rendering Improvements:
- Implemented support for sky probes in games using shader-based rendering.
- Added support for Shader Model 2.0+ in the new terrain baking approach.
  - Falls back to the previous compute shader approach for unsupported draw calls.
- Optimized shader compilation for better performance and reduced boot times
- Shader Handling and UI Rendering
  - Improved shader performance by allocating vertex capture buffers in VID.
  - Implemented a way for users to ignore object2world transforms for improved compatibility with shader based games.
  - Implemented geometry hash for sky boxes.
  - Implemented vertex shader hash as a hash component.
  - Ensured UI rendering in draw calls that use shaders.
- Vertex Attribute Handling: Removed the need for the invertedUV attribute.
Code Clean-up and Optimization:
- Made Remix leak- and circular reference-free.
GPU Print Functionality:
- Added basic GPU print functionality.
- Supported printing of float4 values with one value per frame.
Bridge Improvements:
- Enhancements and Optimizations:
  - Added support for multithreaded devices and module level calls for games that use those D3D features.
  - Added proper support for games that use CreateDeviceEx() function parameters.
  - Added support for D3D Query() functions.
  - Generally made things more thread safe for any multithreaded interactions between the bridge client and server components.
  - Added alwaysCopyEntireStaticBuffer option to bridge.conf settings, which is off by default but can be used for certain games that don't follow the correct way of copying buffers during lock/unlock operations and require this workaround.
  - We now ensure that when we use DirectInput for input capture we inject ourselves into the system libraries rather than a local copy that might exist in the game directory.
  - We added GitHub Actions for per commit bridge builds to produce debug, debug optimized, and release packages. In most cases the release package should be used, but the other two can be helpful for logging additional information and creating crash dumps when trying to troubleshoot certain issues.
  - Added extra logging to debug builds that help understand the nested command flow of longer D3D command sequences, which makes troubleshooting issues a lot easier.
  - We also now log a list of the most recent client and server bridge commands in case of a crash to help with troubleshooting.
- Bug Fixes and Stability:
  - Fixed various issues where the bridge was not handling D3D input or behaving the same way as the system D3D runtime, which led to changes in rendering behavior that could cause crashes, hangs, or visual glitches. As a result games will run much more stable now.
  - Fixed an issue where a game might ask for an impossibly large buffer size to be copied. Now, in those situations, buffer size will be kept to a maximum limit.
  - Fixed an edge case that could cause the bridge server to exit prematurely under certain circumstances.
  - Fixed issues with reference counting for textures and surfaces, which could lead to instability and crashing.
  - Fixed an issue where releasing a D3D volume with a parent texture could lead to a crash.

Release Notes

The Remix Runtime Bridge is now open source on GitHub! You can find the repo here!
Many Bridge improvements have gone into this release to address various game compatibility issues:
- Fixed issues with shader parser logic that helps with Shader Model 2+ games.
- Fixed surface data pitch issue that was leading to crashes in some games.
- Added support for games that change the main window handle on Reset().
- Allow null vertex declaration on server to fix unnecessary failures in some situations.
- Properly initialize render state according to the official DirectX9 documentation to fix geometry corruption in some games.
- Handle CreateTextureXXX() calls with levels = 0 to fix geometry corruption in some games.
- Fixed mouse input processing for games where the mouse pointer would not move in the game or with the Remix menu opened, and added other DirectInput fixes for games using different exclusive modes. Also added optional input message pump hook that is needed for some games.
- Better matching of the native D3D9 behavior when dealing with shaders and swapchain initialization.
- Added more input validation on client and server side – the server is now properly returning failure codes to the client where failure is allowable.
- Added DPI awareness to the bridge client so that the game window gets scaled and mouse input is handled properly on displays with higher than 100% DPI.
- Optimized how the SharedHeap works to reduce crashes at launch and require less finetuning of its settings. Since the SharedHeap can still lead to issues in certain games we switched it to be turned off by default, but it can be enabled in bridge.conf with the useSharedHeap setting.
- Added forced window client option client.forceWindowed to bridge.conf.
DXVK-Remix improvements and game compatibility fixes:
- Improvements to culling issues–Remix now includes an initial set of heuristics to work around engine-side culling.
- Improved handling of alpha-tested geometry that uses fractional ("feathered") alpha.
- Improved detection of shadow volumes.
- Support for capturing normals in vertex capture path.
Improvements to RTX Remix menus and documentation: expanded and clarified the existing documentation, and added tooltips in the UI to make it more accessible.
Debug symbols for the release are now available in a separate remix-0.2.0-symbols.zip package to make debugging the source code from the compiled binaries easier.

remix-0.1.0

6461501

remix-0.1.0

Initial release of NVIDIA RTX Remix Runtime, containing precompiled binaries for the dxvk-remix and bridge-remix repos.

Changelog

Since the latest update of Portal with RTX, the following updates have been made to Remix:

Bridge

remove dependency on native d3d9 in the bridge

Compatibility

A complete overhaul of our geometry hashing and processing system. Please note: these changes will enable asset replacements with this runtime to work with the Remix creator toolkit. This release still works with Portal with RTX with certain directory renaming steps (see below) but pre-existing mods that rely on Portal RTX runtime for asset replacement will stop being supported in future Remix releases.
A new sky handling system which better improves visual compatibility with native rasterization
Added a view distance feature for fading distant objects improving visual compatibility with raster
D3D9 TCI flag support for procedural texcoord generation
Fused world/view transform feature
Support for implicit swapchains

Various UX improvements including a simplified graphics settings menu, more tooltips, and highlighting objects in the world on mouse-hover
Expose more of the texture pickers we used in Portal via the UX
Improved fallback light controls (for games with no lighting)

Other

An early prototype of multiple mod stacking support (ex: for modding existing remastered RTX titles like Portal With RTX)
Temporary removal of DLSS Frame Generation
CPU Performance optimizations for Opacity Micromaps
A fix for Chell's hair in Portal
Lots of compatibility related bug/crash fixes
Path-tracing image quality improvements (reduced noise & newer denoisers)

Portal with RTX and new runtime

To get Portal with RTX working with the RTX-Remix OSS:

Rename 'lss' dir to 'rtx-remix'
Add a new dir under 'rtx-remix' named 'mods'
Move 'rtx-remix/gameReadyAssets' to 'rtx-remix/mods' (so 'rtx-remix/mods/gameReadyAssets')
Rename 'rtx-remix/mods/gameReadyAssets/replacements.usda' to 'mod.usda'
