Valve has officially released Proton 11 into its final state for Steam Deck and Linux users to enjoy, after a series of betas in the past few months (the first of which arrived back in April). After going through five beta updates and numerous experimental changes, the latest version, labeled Proton 11.0-1, is now available in the stable release channel.

The update is a significant one, especially for Steam Deck owners, as it expands game compatibility and fixes a wide range of issues. Most notably, 18 additional games are now playable, with several classic titles finally running properly without relying on Proton Experimental – the branch treated as a testing ground for Valve’s compatibility layer.

New playable games in Proton 11.0-1

Now playable (previously worked with Proton Experimental)

• Universe Generator: The Golden Sword
• DCS World Steam Edition
• Resident Evil (1996)
• Resident Evil 2 (1998)
• Dino Crisis
• Dino Crisis 2
• From Dust
• Blaite
• Don’t Die Dateless, Dummy!
• METAL GEAR SURVIVE
• Warhammer: Vermintide 2
• Metal Fatigue
• SHOGUN: Total War

Newly playable

• Unknown Faces
• Gothic 1 Classic
• X-Plane 12
• Breath of Fire IV
• Deadly Premonition

Some of these games previously required Proton Experimental to work correctly, while others had compatibility issues that prevented them from running properly. With Proton 11.0-1, they should now offer a much smoother experience on the Steam Deck.

Beyond new game support, Valve has also addressed bugs affecting many popular titles. The update fixes launch problems in Far Cry 4, restores proper keyboard functionality in Age of Empires II: Definitive Edition, removes windowed-mode flickering in Chrono Trigger, fixes intro video playback in BlazBlue Centralfiction, and resolves a bug where Hollow Knight incorrectly detected the Steam Deck’s Steam button as the left trigger.

VR users also receive some welcome improvements. Valve says No Man’s Sky VR is playable again after support was improved, while Microsoft Flight Simulator now features better VR controller tracking.

Several launcher-related issues have also been resolved. REDLauncher, used by games such as Cyberpunk 2077 and The Witcher 3, now exits much faster instead of taking a long time to close. Valve also fixed problems caused by recent updates to the EA App, making many EA games playable again while restoring proper Steam Overlay support.

Under the hood, Proton 11 includes updated versions of several core components, including DXVK, VKD3D, Wine, and Wine Mono. Valve has also added a newer version of FEX, which improves support for ARM64EC builds.

Another useful addition comes through an updated version of Xalia, Valve’s launcher controller support tool. It now adds controller navigation for more launchers and installers, including games such as Final Fantasy X/X-2 HD Remaster, Red Faction: Armageddon, Zero Escape: The Nonary Games, Metal Slug XX, Batman: Arkham Asylum GOTY, and several classic Resident Evil titles.

These were only some of the many changes and improvements introduced in the update. For the full list, you can check out the complete changelog on GitHub. If you already have the Proton 11 beta installed, the stable release should download automatically. Otherwise, Steam Deck users can manually install it by searching for Proton 11 in the Steam Store.
