Valve also published an Arm64 flavour of Proton 11 tied to the Steam Frame headset effort, opening better native support paths for Arm-based PCs and headsets. (pcgamer.com)
Valve has pushed out the first Proton 11 beta, restoring compatibility for many Electronic Arts games after a recent EA Desktop update broke them on Linux and Steam Deck. (github.com) Proton is Valve’s Windows-compatibility layer for Steam Play, built on Wine, and it lets Windows-only games run on Linux systems including Steam Deck. Valve’s new `proton-11.0-1-beta1` release appeared on GitHub about two days ago. (github.com, github.com) Valve’s release notes say the beta “fixed many EA games being unplayable after a recent EA Desktop update” and also fixed the Steam Overlay in many EA games. The same build adds support for SteamWorks Software Development Kit 1.64. (github.com) Valve also marked 18 more Windows games as playable in this first beta. The list includes Gothic 1 Classic, X-Plane 12, Breath of Fire IV, Deadly Premonition, DCS World Steam Edition, Resident Evil 2 from 1998, Dino Crisis, Warhammer: Vermintide 2, and SHOGUN: Total War. (github.com) The update reaches beyond launcher fixes. Valve says it restored No Man’s Sky virtual reality mode, fixed virtual reality controller tracking in Microsoft Flight Simulator, and repaired Rec Room after a recent game update. (github.com) Valve has been tying more of its Linux work to new hardware plans since it unveiled Steam Frame in November 2025. PC Gamer’s Steam Frame coverage says Valve is also bringing SteamOS to Arm and using a new FEX translation layer for x86 and Arm software. (pcgamer.com) That Arm push matters for Proton because most PC gaming handhelds and desktops still use x86 chips, while newer headsets and some low-power devices use Arm chips. An Arm64 flavor of Proton 11 would give Valve a more direct way to run Windows game code on those systems instead of relying only on x86-targeted builds. (pcgamer.com, github.com) PC Gamer’s hardware coverage says Valve was still targeting 2026 launches for Steam Machine and Steam Frame as of March 7, 2026, even after supply concerns around memory and storage. That keeps Proton 11’s beta work lined up with a year when Valve is trying to widen SteamOS beyond the original Steam Deck. (pcgamer.com) For Steam Deck and Linux players, the immediate test is simpler: whether EA games launch again without workarounds. Proton 11 beta is now the branch to watch for that answer.
