I’m not OP but for me I end up having trouble with games and maintaining dual boot for it isn’t worth it. Most recently I was trying to install gamescope on PopOS LTS for retro gaming, but it was too old of a distribution for gamescopes dependencies, so I upgraded to Cosmic and it broke my software KVM. I use PopOS because it has great NVIDIA support and I’ve run into issues before with other distros.
At that point I switched back to windows but I’ll try again after a few months. I always keep trying.
I think if I didn’t play games I’d be fine with Linux. I hate Windows except that everything just works.
With Steam, I haven't seen a game that doesn't work yet. I was just playing Clair Obscur yesterday, it worked great. I don't know about Gamescope, but I think you can run whatever Windows thing you want through Proton and it'll probably work well.
It’s been hit or miss for me. I mostly play strategy games. I often get weird game graphics, flickering and things like that that go away when I give up and reinstall windows.
