Proton-CachyOS, ein von CachyOS gepflegter Proton-Fork mit zusätzlichen Patches und Performance-Optimierungen, wurde in der Version 11.0-20260702 veröffentlicht. Das Tool dient als Kompatibilitätsschicht, mit der Windows-Spiele über Steam und Lutris unter Linux laufen.

Das Release basiert auf Proton Experimental 11.0-20260701b und bringt einen neuen Pipewire-Audiotreiber (winepipewire.drv), der standardmäßig aktiv ist und die Umleitung über PulseAudio überflüssig macht. Zudem wurde FSR4 4.1.1 für alle unterstützten Grafikkarten integriert und die zugehörigen Umgebungsvariablen vereinfacht.

• Proton (SLR and Native)
  • Updated to Proton Experimental 11.0-20260701b
  • Added winepipewire.drv driver for Wine to directly use Pipewire instead of using winepulse.drv and going through pipewire-pulse.
    • The driver is enabled by default. To disable it and use winepulse.drv set PROTON_USE_PIPEWIRE=0.
    • You can also use WINE_AUDIO_DRIVER to set the list of drivers for wine to choose from. The default list is pipewire,pulse,alsa.
  • Imported amdxc64 changes from Proton-EM to enable FSR4 4.1.1 on all supported hardware.
    • The amdxcffx64.dll driver dll is copied automatically, there is no need to use PROTON_FSR4_UPGRADE any more.
    • Removed PROTON_FSR4_RDNA3_UPGRADE and PROTON_FSR3_UPGRADE (renamed to PROTON_FFX3_UPGRADE).
  • Added the DualSense 5 patches that were skipped previously due to the rebase to Proton 11.0.
  • Added some stubs to dnsapi which should allow iRacing to run. The anti-cheat blocks the game from fully working.
  • Fixed Surviving Mars crashing after loading into the start menu along with some other audio-related issues.
  • Fixed compile-time configuration for GStreamer, specifically enabled glib-checks again.
  • Updated d7vk to version v1.12.
  • Improved the Vulkan version detection and the underlying API to also check for driver versions and extensions in the future.
  • Added PROTON_ADD_CONFIG environment variable to supply configuration through compatibility configs instead of environment variables.
  • Enabled the compiler item in DXVK_HUD by default.
• Proton (SLR specific) / Proton (Native specific) / Wine (Standalone): None
