A massive double-release for the Linux and SteamOS compatibility layer has landed. GE-Proton 11-3 and the preceding 11-2 update bring a wide array of technical upgrades, including full OptiScaler integration, AMD FSR4 improvements, and an extensive list of specific game fixes for titles like Cyberpunk 2077, Star Citizen, and Dragon's Dogma 2.

Quick Facts

  • Platforms: PC via Linux and SteamOS (also supports ARM64 devices via FEX).
  • Key Additions: Complete OptiScaler download, injection, and Protonfixes integration alongside AMD FSR4 version selection.
  • NVIDIA Updates: Added NVIDIA compatibility libraries including NVAPI, CUDA, NVENC, NVML, and OptiX.
  • Controller Haptics: Added wired USB haptics and mono-speaker audio output for DualShock 4, DualSense, and DualSense Edge controllers.

Game Fixes and Media Rework

The latest updates resolve multiple crashes, visual glitches, and audio delays across a variety of titles. Star Citizen sees a repaired WineOpenXR Vulkan integration and external VR support. VRChat receives fixes for remote HLS and YouTube playback, audio, seeking, and queued videos. Meanwhile, Dragon's Dogma 2 and Riddle Joker both benefit from fixes addressing green video padding bars.

Cyberpunk 2077 updates reduce audio delays and fix a null-handling failure. Other specific adjustments include fixes for startup video crashes in Yakuza 5 Remastered, MPEG video display errors in GTA San Andreas, and black-screen video playback issues in favorite visual novels and Witch on the Holy Night. Upstream fixes for Diablo IV and Marvel Rivals have also been imported to ensure proper execution.

The underlying media stack has been rebased on newer Wine revisions using an updated FFmpeg and winedmo video stack. This rework adds remote HLS URL support, improved media-session state transitions, and better audio clock recovery.

Controller Support and Wine Wayland Improvements

Controller functionality expands significantly with wired USB haptic feedback and mono-speaker audio routing configured for Sony's DualShock 4, DualSense, and DualSense Edge controllers, which have been tested and confirmed working in titles like Stellar Blade and Spider-Man Remastered. Hotplugging and switching between these controllers are now fully stabilized under a standardized PulseAudio implementation.

On the system side, the release updates bleeding-edge Wine revisions and rebases the EM-11 Wine Wayland patchset. These adjustments improve layered windows, fractional scaling, pointer warping, keyboard mappings, and window restoration. GE-Proton 11-3 specifically functions as a hotfix release to address compilation failures on aarch64 and resolve a double-input bug linked to the steam desktop global virtual device when wine-wayland is enabled.

Player Impact Summary

Players utilizing SteamOS, Linux distributions, or external launchers like the Heroic Games Launcher will find that GE-Proton 11-3 substantially improves graphical scaling options, VR compatibility, and media playback stability. While Valve's official Proton remains recommended for standard Steam usage, GE-Proton provides essential troubleshooting capabilities for demanding titles outside of Steam and on alternative hardware configurations.
