And since Proton is built-in to Steam for Linux, there’s honestly no extra effort to get games to run. In 99% of cases, you click “play” and Steam downloads whatever compatibility layer it needs to run the game on Linux (same thing that Steam Deck uses).
Some games don’t work (almost anything with anticheat), but anything that works on Steam Deck works on Linux, because they’re the same thing from a software perspective.
