That was before Steam Deck and Proton, though, so I should probably test it all again.
The steam deck is exactly what convinced me to give Linux a whirl on my main gaming pc again. Everything that runs on a steam deck should run on any Linux PC. So far zero regrets, performance is on par with what I was seeing on Windows, proton is an absolutely bonkers development.
I do have to end this by saying I don’t do online gaming so I have not had to deal with anti-cheat bullshit that doesn’t want to work on anything that’s not Windows.
