Valve's Proton 11 beta unlocks more playable games and boosts performance for Steam Deck and Linux fans

Valve's latest Proton 11.0-beta1 is here, bringing broader game compatibility and improved performance for Steam Deck and Linux users. The release also lays the groundwork for further improvements expected in the near future.

The biggest highlights include expanded support for classic and newer titles. Several games that previously required Proton Experimental now run officially, including classics like Resident Evil 1 and 2, Dino Crisis 1 and 2, SHOGUN: Total War, Warhammer: Vermintide 2, Metal Gear Survive, and DCS World Steam Edition.

Valve has also massively expanded the playable library, adding new titles, including Gothic 1 Classic, X-Plane 12, Breath of Fire IV, Deadly Premonition, and Unknown Faces. Additional fixes cover other classic titles, including Chrono Trigger, Metal Gear Solid 2, and Call of Duty 2.

Proton 11 is based on Wine 11 - a new compatibility layer - which brings NTSync kernel driver support by moving parts of the NT synchronization model directly into the Linux kernel. NTSync improves Proton's ability to run Windows software more reliably, potentially reducing CPU overhead and improving frame rate consistency. With this, older and newer titles like Crimson Desert and Resident Evil: Requiem should now run more smoothly.

The beta also introduces technical updates, such as FEX-2604 and ARM64EC builds, suggesting that Valve is developing a compatibility layer for its upcoming VR headset. These changes also indicate a broader push toward ARM compatibility and potential support for future hardware beyond traditional x86 platforms.

Valve has also improved the handheld experience by updating Xalia, enabling better gamepad support within installers and launchers so users can navigate without a keyboard or mouse. The update brings a lot more, which Linux gamers should start to see once they download the beta, including improved GPU utilization, better multi-monitor and scaling behavior, fewer launcher issues, and an overall "launch and play" feel. Proton 11.0-beta1 is available through Steam settings, where users can opt into the beta and test the latest improvements.
