While Proton is great, it helps no one to suggest it's a solution to making all games work. There are absolutely enormous multiplayer titles still unavailable on Proton, if you can't play the games your friends play who cares if 99% of the rest of the Steam library works?

Again, I think Proton is great, and only getting better. It is not though a drop in replacement for a Windows gaming machine, for most people, yet.
