Valve’sSteam Deckcan run thousands of PC games practically anywhere. The console uses avariation of the Linux operating systeminstead of Windows, running games through a compatibility layer called Proton. Most of the time, games verified by Valve will play perfectly fine, but sometimes there are sneaky bugs that can be remedied by switching up the Proton version.
Naturally, the latest version is intended to bring all the fixes of the previous builds and more, but sometimes games get a bit funky with subtle changes. You can test different versions of Proton per game in your library rather than adjusting your entire collection. We’ll show you how to change the Proton version on your Steam Deck and where to check for the latest compatibility notes.
What is Proton?
Proton is a compatibility layer that allows games to run on the Steam Deck and its Linux-based operating system, even if they were initially designed for Windows. Not technically an emulator, the Proton layer translates rendering platform-specific APIs like DirectX and displays them as accurately as possible. Proton is an open source fork of WINE (Wine Is Not an Emulator), a previously-existing compatibility layer for running Windows software on Linux PCs.
