Valve has rolled out a new stable Proton update, and it’s a big one. The latest release brings a long list of fixes, performance improvements, and expanded compatibility, making even more Windows games playable on Linux (including the Steam Deck’s operating system, SteamOS). Many of these changes were previously tested in Proton Experimental, but they’ve now made their way into the stable Proton 10 branch.

One of the highlights of this update is support for 19 additional games that are now considered playable without needing experimental builds. This includes a mix of flat-screen and VR titles, as well as some well-known names. Games like Metal Slug: Awakening, Summoners War: RUSH, REACH, and Distant Worlds 2 are now officially playable through the stable Proton release. For Steam Deck users, this means fewer workarounds and a smoother out-of-the-box experience.

What does the update offer?

Now playable (previously worked with Proton Experimental):

• Surgeon Simulator: Experience Reality
• Changeling VR

Beyond new playable games, the update focuses heavily on fixes. Several major titles that had issues are now in much better shape. Problems affecting games such as Far Cry 5, The Outer Worlds 2, Dragon’s Dogma: Dark Arisen, and Assassin’s Creed Shadows have been addressed.

Controller support also received attention. DualSense haptics are now working properly in most games that support them, and overall support for Sony controllers has been improved in titles like Tekken 8. This is especially important for Steam Deck users who rely on controller features rather than keyboard and mouse input.

The update also fixes several regressions introduced in earlier Proton 10 builds. Games such as Chrono Trigger, Lost Planet: Extreme Condition, and Killer Instinct are once again playable after being broken by previous updates. Video playback issues that affected multiple games, including AQUARIUM, have also been resolved, along with audio fixes and font rendering improvements across different languages.

On the technical side, Valve updated several core components. The SteamWorks SDK has been bumped to version 1.63, Wine Mono is now at 10.4.1, and newer versions of vkd3d-proton and vkd3d are included. These changes help improve DirectX compatibility and overall stability going forward.

For Steam Deck owners, the update should install automatically if Proton 10 is already installed. If not, Proton 10 can be downloaded directly from the Steam Store.
