Can confirm. Have been playing games on Linux for years now and with proton, the vast majority of games just work. And there's protondb to fix up the rest.
The one game I couldn't actually get working was Escape from Tarkhov because it has some windows-only anticheat. I.e. the developers chose to make it not work, not an accident.
