Proton 10.0-3 released bringing lots of improvements for gaming on Linux, SteamOS, Steam Machine

Valve released Proton 10.0-3, the latest main stable version of the compatibility layer to run Windows games on Linux / SteamOS machines like Steam Deck. And now the Steam Machine and Steam Frame too of course whenever they arrive sometime in 2026.

The secret sauce that makes Linux gaming so amazing now, enabling tens of thousands of games to run well, just not those with certain types of anti-cheat which is a continuing problem. It's been a long road to get here, with Proton 10 being in some form of Beta since April. But it's here now!
