i know that some games arent compitable and been to the site that shows which game is and which is not, and i also know most mods dont work on linux version which is a boomer (skyrim and rimworld mostly)?
so for gamers, why did you change to linux being a mostly a gamer?
It really depends, what you want to play. Old games run great for me, emulation is also good.
New games mostly work if they are not competetitive multiplayer.
Mods also mostly work for the games I play (FTL and Celeste e.g.), also mods through steam workshop like in Tabletop Simulator just work for me.
What didn’t work are as mentioned some multiplayer games that are too harsh on anti cheat. SMITE e.g. works, but LoL doesn’t.
As others mentioned, its best to have either a native version or an entry in ProtonDB with gold or platinum.
