PC gaming on linux these days is joy these days. The main games you're likely to struggle with are games that require some windows kernel level anti-cheat software running, so some online multi-player will not be playable for that reason. Proton, wine, and the ecosystem have evolved a lot in the last couple years to the point that I'm surprised when a game can not run on linux. Occasionally, you need to look at https://www.protondb.com/ to see if there is some startup option that needs to be added to get the game to run. If you're into single player games, Linux is generally a really solid choice.
