Oh wow, nice! I especially appreciate the ProtonDB link-- I’d known about Proton, but not ProtonDB. :) And that’s awesome, re GW2 especially!
I’m thinking I’m going to try Pop!OS… I was reading reviews etc. of various gaming/newbie Linux stuff on [itsfoss.com](It’s Foss) and they’re a big fan, and Pop seems pretty readymade for gaming stuff. I plan to put it on a flash drive & test it before dual booting to it, and if I’m not a fan, Linux Mint it is! I tried that once before, years ago.
