I have a lower-mid tier (Ryzen7 2700 or 2700x, I don’t exactly remember right now, Nvidia GTX 1650, 16gigs of RAM,) and I can game just fine at 1080p. Granted I’m not exactly worried about 4K or 666 FPS or whatever the hardcore gamers are into these days, but most games work well with proton and steam. Some even run better through proton than they do in Windows natively.
My favorite system message is GRUB’s “bailing out, you’re on your own. Good luck”
