Valve has updated Proton, its compatibility layer that allows Windows games to run on Linux, by rebasing it onto a newer codebase and adding fresh fixes. The update matters because Proton underpins Linux gaming and the Steam Deck, so improvements widen the range of Windows titles that Linux users can play smoothly.

Among the notable changes, the updated release brings support for playing Resident Evil, expanding compatibility for players on Linux systems. The rebasing work keeps Proton current with upstream developments, which typically improves performance and stability across a broader library of games.
