No offense but if you're seriously using Linux for gaming than then idk what to tell you most games don't even support Linux and those who do normally stop after a while f.e. Rocket League even years before Epic got involved
Where have you been the last couple of years? Thanks to steam and their fork of wine you can play a large chunk of games on Linux.
Steam Deck runs on Linux, maybe think for a moment before pulling bs arguments from your behind.
