I have never been a big fan of multiplayer competitive games. So thankfully I don't have to worry about Anti-Cheats, which continues to be the main thing holding back some games working on Linux. At this point most single player or cooperative multiplayer titles that don't require an anti-cheat work great with Valve's Proton.

Also, AMD GPUs work pretty great in Linux. I know they're not as popular as nVidia, but I've had very good functionality from them in Linux.
