Personally, I really only game on my steam deck anymore. Occasionally I play on my personal laptop when I'm on the road for work and I don't feel like holding the deck up, and that's running endeavourOS. I dual boot windows and endeavourOS on my desktop at home, which my son uses to play sometimes. Lately he's just been playing on Linux instead of rebooting into Windows without issues. We're finally in a place where most games just work.
