Valve has released Proton 11 beta 2, a focused maintenance update for its Windows game compatibility layer on Linux. The update targets a handful of specific issues, including a lockup triggered by interactions with the EA App, which has been resolved through an update to Xalia 0.4.9.
The release also addresses a regression introduced in Proton 11 that caused low FPS during the intro cinematic in They Are Billions. On the graphics translation side, vkd3d-proton has been brought up to the proton-20260410 branch, pulling in fixes for Marvel's Avengers among other improvements. The full changelog for the Proton 11 beta series is available in the beta 1 release notes.
