I switched about two weeks ago to PopOS on my gaming PC. Everything works smoothly now, but I am also highly knowledgeable with computers and work as a sysadmin. Even PopOS isn’t plug and play for someone who just turn on their PC and launches Steam to play some games. Whilst all my games work now, almost every game requires a small tuning, some small fix, some config changing to work properly. I wouldn’t recommend Linux gaming to those who aren’t technically capable enough to know how to install an OS or research distros without following a tutorial.

Depends. On Ubuntu? Sure. On Wayland Arch? Good luck.
