There's still room for improvement, but Linux gaming has come a long way in a short time.
I remember when Proton launched it was like magic playing games like Doom and Nier Automata straight from the Linux Steam client with excellent performance. I do not miss the days of having the Windows version of Steam installed separately.
Iam using a Laptop with a thunderbolt connected gtx1070. Does someone have experience or tips using linux and gaming with a setup like that. That and (solidworks) are the last reasons i didn't switch already.
because @clegko mentions shit support :( , maybe look at the framework laptop for your next upgrade? they are doing some stuff with replaceable parts, and the newest one even swappable gpu's.
Sadly my current laptop is kinda new (half a year) and I searched way to long, because I have a weird taste. (I am used to hardware mouse buttons, so thinkpads are mostly the only option. I also dislike the odd haptic gummy feeling of premium thinkpads, which only some models don't have (for example T490s, T14sG1 and G2) or the Yoga X1 series which is aluminum, which I gladly found a nice deal of the 2019 model.
