I'm not here to dish out undue praise, but Proton really is incredible. Unless a game has intrusive anti-cheat or DRM, you can expect most Windows titles to "just work" these on Linux these days. Valve has put a tremendous amount of work into this project, it's almost hard to describe.
It’s really long-term planning. Valve gets shut for not following through on game projects these days, but building Proton and preparing Linux for gaming will yield 10x to 1000x the returns on making a game…
Let’s not forget they were the single most important player in the whole VR Revolution. Oculus took the huge improvements that were made inside valve in VR and took the team to FB. But pretty much all the major breakthroughs were done at Valve, not oculus.
