CXPatcher

A patcher to upgrade CrossOver dependencies and improve compatibility

This is an unofficial patcher for CrossOver and CodeWeavers is not - by any means - involved in this or has anything to do with this app, and although has been tested, this software may render the app unusable or unstable, USE AT YOUR OWN RISK, this also will void any official support from CodeWeavers, If you still need support from CodeWeavers, download the original unmodified app and please don't report problems to them after your app is patched.

If you have any issues after your app has been patched you can download a new copy of CrossOver.

What version of CrossOver does it support?

Currently only 22.x.x

What MacOS does it support

Ventura (13) or newer Currently GPTK requires MacOS Sonoma

What does it do?

This patcher will upgrade your CrossOver app with the latest DXVK and MoltenVK patched for improved compatibility, and dramatically extends compatibility with Unreal engine 4 games.

What does it NOT do?

• Games with anti-cheat or anti-tamper will not work

• DX12 games will not work unless playable via the popular -dx11 option DX12 games will now work via GPTK

Instructions

You need to have an unmodified version of CrossOver, you can download it at: https://www.codeweavers.com/account/downloads. Please make sure the app has been registered or ran at least once, to make sure the latest DXVK is activated properly. You may need to switch off DXVK and on again, if you don't you will need to re-download it. If the patcher renders the app unusable you can either use the restore function (see instructions below) or download it again from the website, it doesn't do any permanent modifications to your 'bottles'.

Installation

Direct Download

You can download the latest version directly from the Release Page.

Homebrew

Alternatively, you may use Homebrew. See the homebrew-CXPatcher repo for detailed instructions.

New Bottle path

CXPatcher will override the default bottle path to have its own folder prefixed with 'CXP' in the same one that contains the 'Bottles' folder. That's because lots of users keep having trouble when using old bottles created with the original Crossover. This way you'll be forced to create a new bottle just for the Patched Crossover so that you'll no longer have this kind of issue.

If you don't like that you can disable it, it's enabled by default as you can see in the picture below:

Patching with gptk

There are new upcoming technologies developed this year that are capable of running DirectX 12 games and now you can have those embedded in CrossOver! In order to integrate that in CrossOver you just need switch on "Integrate D3DMetal (GPTK)"

• now you can patch CrossOver as usual via either drag'n'drop or file selector (click in the drop area)
• enjoy your DX12 games!

Restoring a patched app to the original app

Maybe you changed your mind and prefer to use your original CrossOver app. You can restore by going to the file -> restore menu

Upgrade from an old patch

If you patched from an old version and you just want to update the patched CrossOver app just turn on the option and drag 'n drop

Troubleshoting

If your env vars doesn't work anymore or can't enable/disable fast math: use the env variable CXPATCHER_SKIP_NTDLLHACKS=1 and then any env var should work as usual For other issues: try: NAS_DISABLE_UE4_HACK=1

Color profiles for UE4 games

You can change the way the colors are processed in UE4 games.

Examples

disable color profiles

(old greyish colors but may improve performance or fix dark or oversaturated colors)

NAS_TONEMAP_C=0

Color profile for Stray

NAS_TONEMAP_C=clamp({inputColor} * float3x3( 0.2126 + 0.7874 * 1.5, 0.7152 - 0.7152 * 1.5, 0.0722 - 0.0722 * 1.5, 0.2126 - 0.2126 * 1.5, 0.7152 + 0.2848 * 1.5, 0.0722 - 0.0722 * 1.5, 0.2126 - 0.2126 * 1.5, 0.7152 - 0.7152 * 1.5, 0.0722 + 0.9278 * 1.5 ) * 2 - float3(0.28, 0.2, 0.16), 0.0, 1.0)

NAS_TONEMAP_C uses standard MSL shading language, as long as it's done in one line, you can use {inputColor} as a variable and modify the colors, or give any effect you like using matrix transforms, WARNING: do not copy paste any code from unknown sources, and do this only if you know what you're doing, otherwise, have fun!

Note: you may need to use CXPATCHER_SKIP_DXVK_ENV=1 to override built in settings for games that already have a profile NAS_TONEMAP_C, also only works for UE4 games.
