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.
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.
