The new release also addresses problems affecting several major titles. Proton 11.0-2 includes fixes for games such as Marvel Rivals, Diablo IV, Hitman World of Assassination, Forza 6, Helldivers 2 and others. Some of these games had experienced crashes and other issues following recent patches.

The latest stable version of Proton officially supports the following titles:
Seven additional games have been added to Proton Experimental. Their compatibility is expected to eventually arrive in a future stable Proton release:
SteamOS users can enable Proton Experimental on a per-game basis through the game’s properties. Find the desired title, open Properties, go to Compatibility, select Force The Use of Specific Steam Play Compatibility Tool, and choose Proton Experimental.
Proton Experimental can also be enabled system-wide. To do so, press the Steam button, open Settings, go to System, and turn on Enable Developer Mode.
The complete Proton 11.0-2 changelog is available on GitHub. Valve’s previous Proton update focused primarily on expanding compatibility with retro games.
