From the sample size of my two friends I don't think Nvidia GPUs are that much of a problem anymore on Linux. I don't personally own an Nvidia GPU so take that as you will.
Certain multiplayer games like CoD because of its anticheat are definitely unplayable on Linux. Only reason I still have windows is for that and Phasmophobia. But I think I can get Phasmo multiplayer running if I tinker with it. Maybe.
Well you won't hear me argue for that. I don't come off like that do I?
I wouldn't recommend Linux to my mother for instance. She may use a laptop for work all the time but thats about as far as her knowledge goes.
