Valve has released an update to its Proton software, a compatibility layer that allows running Windows games on Linux and other platforms. The new version, labeled 10.0-4, adds several titles directly accessible via Proton Experimental, including Surgeon Simulator: Experience Reality and Changeling VR. This release also tackles specific game hiccups reported by users, such as issues with Evil Under the Sun in French and HDR problems on OLED Steam Decks. Beyond these fixes, Proton 10.0-4 brings general compatibility enhancements and user experience improvements, including better controller feedback handling and audio tweaks for various games.
Proton 10.0-4 released
Valve has dropped an update to its Proton software today, that clever compatibility layer you can use to run Windows games on Linux and other platforms. The new version is labeled 10.0-4.
One neat thing with this latest release is it adds several titles directly accessible via Proton Experimental, the bleeding-edge option for testing new games. Checkers fans will find Surgeon Simulator: Experience Reality now playable, while VR enthusiasts can get into Changeling VR or experience REACH and Fellowship on their Steam Deck (or elsewhere). Titles like Death by Scrolling and The Sims 4 expansion packs are also welcome additions this cycle.
Beyond adding more titles to the fold, Proton 10.0-4 tackles some specific game hiccups reported by users. If you tried Evil Under the Sun in French before, you'll likely find it works now. Similarly, AMD GPU owners running Far Cry 5 should see an old-driver nag message vanish. And there's always that frustration with HDR; this update fixes OLED Steam Deck HDR issues.
Then there are some broader enhancements for general compatibility and user experience. Proton has long offered haptics support for games like For Honor, but now it brings better controller feedback handling to Tekken 8 via DualSense tech. Sony controllers get proper support in that game too. Also patched up was audio weirdness seen cropping up in Rocket Jockey.
On the technical front, this isn't just one big lump of changes either. Proton pulls in updated versions for core components like Wine Mono (10.4.1) and vkd3d, which include improvements to the proton version itself (v1.18). It even incorporates SteamWorks SDK 1.63.
Alongside all that, there's a whole host of other smaller bug fixes and performance tweaks impacting various titles and general system stability. Think faster loading times for some Xbox Game Studios games or smoother action in titles like Ara: History Untold, where GPU errors used to trip things up, this release covers it.
So yeah, another solid round of refinements for Proton has landed from Valve. Hopefully, these fixes mean fewer crashes and quirks for those exploring the Linux gaming landscape (or other systems) with their preferred software layer.
