Version 10.0-20250919

• Proton (SLR and Native)
  • DXVK is under heavy development at the moment of this release. DXVK and VKD3D-Proton have been updated to the latest version but issues might still arise. Reproduce any issues with Valve's Proton Experimental Bleeding Edge and report them upstream.
  • Updated PROTON_(DLSS|XESS|FRS4|FSR3)_UPGRADE cache to hold the compressed archives instead of the extracted DLLs to reduce storage requirements. If you want to remove the old files, delete ~/.cache/protonfixes/upscalers directory, as they won't be automatically removed.
  • The per-game cache is not enabled by default any more as it seemed to cause confusion. You can enable it using PROTON_LOCAL_SHADER_CACHE=1 if you want the previous behavior.
  • Removed GST_GL_WINDOW=surfaceless when enabling Wayland as it is not as compatible as x11. If your game spawns an invisible window on the taskbar under Wayland when playing videos, you can use the previous value to get rid of it.
  • Removed the temporary DISABLE_LAYER_MESA_ANTI_LAG flag when using FSR4 upgrade as Anti-Lag 2 should be working properly now. For information on why this was added in the first place refer to #47.
  • Updated protonfixes to Open-Wine-Components/umu-protonfixes@1cec055.
• Proton (SLR specific)
  • None
• Proton (Native specific)
  • This release won't have a native package in CachyOS repositories or the AUR. The reason is that there is too much work-in-progress in DXVK that might cause breakages, and there isn't a user-friendly way to downgrade CachyOS or AUR packages.
  • Despite the above, the source is present in the repository for anyone wanting to build it locally by modifying the existing PKGBUILD, or from my own repository here.
  • Removed piper, openfst, kaldi and vosk from the build to reduce size and compile time as they were not linking correctly in the native build. They might be included again sometime in the future.
• Wine (Standalone)
  • Removed the "Disable hidraw/Enable SDL" patch as it breaks PlayStation glyphs in games with native DualSense support. You can still disable hidraw just like in Proton with PROTON_DISABLE_HIDRAW=1. Thanks to @NelloKudo.
  • Imported upstream wine patches to enable wow64 on multilib builds using WINEARCH=wow64. Using wow64 should fix games that don't play videos due to missing lib32 ffmpeg and gst-plugins in Arch/CachyOS but also might cause issues with various applications and installers.

Warning
