Version 10.0-20250819

• Proton (SLR and Native)

  • This is a re-release of 10.0-20250807 re-based on top of experimental-10.0-20250819 with some additional features and fixes.

  • The _ntsync branch has been merged for this release as part of the main branch. Disabled by default.
    Note: To use NTSync you have to set PROTON_USE_NTSYNC=1. Do not trust Mangohud's indicator, it falsely reports that it is using NTSync without this environment variable while in reality it's using FSync/ESync. Verify with lsof /dev/ntsync. This is not the same patchset as in Proton-GE/Proton-EM, it's compatibility might differ.

  • Added dxvk-sarek as an optional DXVK replacement for older GPUs that don't properly support Vulkan 1.3. It is using the async branch, so it SHOULD NOT to be used with games using anti-cheat or multiplayer games in general. You have been warned. Use PROTON_DXVK_SAREK=1 to enable.

  • Fixed an issue with PROTON_NVIDIA_LIBS causing games to hang if it was enabled and then disabled.

  • Skip cache cleanup on NVIDIA for per-game shader caches.

  • Allow DXVK_NVAPI_DRS_SETTINGS to be overridden by the environment when PROTON_DLSS_UPGRADE is used.

  • Changed how upscaler DLL replacement works to allow for multiple of PROTON_FSR4|FSR3|DLSS|XESS_UPGRADE to work simultaneously. This is meant to accommodate software such as Optiscaler to find updated DLLs for different upscalers at the same time.

  • Added PROTON_FSR3_UPGRADE to upgrade FSR 3.1 DLLs to newer versions.

  • Did the usual video/audio codec whack-a-mole again, some things might work, some things might break. C' est la vie.

  • Added PROTON_MEDIA_USE_GST and PROTON_GST_VIDEO_ORIENTATION from Proton-GE to support fixes for videos with the wrong orientation.

  • Imported a few upstream commits.

  • Updated protonfixes to Open-Wine-Components/umu-protonfixes@a19a272

• Proton (SLR specific)
  • None
• Proton (Native specific)
