GE-Proton 11-3 brings better OptiScaler integration, AMD FSR4 improvements and lots of game fixes

By /

GE-Proton 11-3 (and 11-2 just before) is a huge release for the popular compatibility layer for SteamOS / Linux.

With this release you can expect to see upgrades and improvements for OptiScaler, AMD FSR4, controller support, video playback and updated versions of various translation layers like: DXVK, DXVK-NVAPI, VKD3D-Proton, D7VK, Vulkan headers, and FEX (for running x86 applications on ARM64 Linux devices).

There’s also a healthy dose of fixes for games like Star Citizen, VRChat, Cyberpunk 2077, Dragon’s Dogma 2, Yakuza 5 Remastered and many more.

Make sure you take a look at the GamingOnLinux explainer on the different Proton versions and the GamingOnLinux guide to install GE-Proton to get started with it. For Steam you generally only need GE-Proton for very specific games as it’s best to stick with Valve’s official Proton for direct support, but GE-Proton is great for outside of Steam like with the Heroic Games Launcher.

release highlights

  • GE-Proton11-3:

    This is a hotfix release:

    • Fixes a bug where the steam desktop global virtual device would still be recognized in-game when wine-wayland was enabled, causing incorrect mappings and double input. Steam Overlay does not work in wine-wayland and subsequently neither does Steam Input since it requires the overlay for profile assignment. (It has always been this way since wine-wayland was added), but now with the desktop profile out of the way the controller input should behave the same as native wine expects it to when wine-wayland is enabled. This does not appear to be a problem with wine-wayland disabled even if steam input is disabled.

    • Fixes compilation failure on aarch64 due to an architecture specific code difference in the wineopenxr decoupling patch (this patch allows VR to work outside of steam)

    • Fixes compilation failure on aarch64 due to the new nvidia libraries only being buildable on x86_64 — they’ve been disabled on aarch64.

    GE-Proton11-2:

    Note:

    I did not have enough time to do thorough regression testing for video playback after making recent changes, however several games that had video playback issues in 11-1 have since been fixed. Many of the VR related issues have also been fixed. I wanted to get this release out because it contains important fixes for allowing Marvel Rivals and Diablo IV to run correctly.
