Improved compatibility with flagship titles
Nearly 3 months after the release of version 10.0-4, Proton has just released the first beta of its upcoming major version: Proton 11, based on Wine 11 available since January 13, 2026. Once again, this new release shows that gaming on Linux is moving forward rapidly.
As a reminder, Proton is a compatibility layer based on Wine designed to run Windows games on SteamOS, a Linux system. Thanks to the work carried out by Valve's teams, some games may even perform better on Linux than on Windows, which is quite a turnaround.
The Proton 11 beta notably brings better support for the EA Desktop client, improving compatibility for several EA-developed games. But that is not the only platform optimized in this new version:
- Rockstar Launcher : improvements have been added for games such as GTA V and Red Dead Redemption 2.
- REDLauncher : improvements for Cyberpunk 2077 and The Witcher 3.
As you can see, Valve's teams are working on title-by-title optimizations and fixes. The changelog for this first beta of Proton 11 also mentions fixes for several games: Helldivers 2, Call of Duty 2, Crimson Desert, Chrono Trigger, Arc Raiders, The Finals, Satisfactory, Titanfall 2, and even the classic Resident Evil 2 (from 1998!).
Five new games are also playable with this version, and were not before: Unknown Faces, Gothic 1 Classic, X-Plane 12, Breath of Fire IV, and Deadly Premonition.
Better performance with Proton 11
Running more titles is one thing, but the in-game experience is another. On the purely technical side, Proton 11 promises very concrete performance gains aimed at making sessions more responsive:
- Better frame pacing management (the consistency of frame delivery).
- Reduced input latency and micro-stuttering.
- Improved handling of graphical interfaces and overlays.
Finally, virtual reality (VR) users get better overall support for games and various VR controllers.
SteamOS running on a Nintendo Switch
Via BlueSky, a modder posted a video showing that he managed to run the Steam platform directly on a Nintendo Switch, thanks to the Proton 11 beta.
To achieve this technical feat, he relied on the translation tool FEX 2604, which converts standard x86 instructions from computers on the fly into a format suited to the portable console's ARM architecture. This is also new in Proton 11, as noted on GitHub: "Added FEX-2604 for ARM64EC builds". It remains to be seen how Valve plans to use this translation mechanism going forward.
