I don't think people know how janky Linux Gaming was a few years ago and how much better it has gotten.
Up until Proton/SteamPlay was introduced, most Linux gamers had 2 or more Steam installation. One for your native games, one under Wine for the unproblematic games, and...1/6 another customized Wine based installation for each of the more problematic games. Lutris and PlayOnLinux were a godsend for managing these installations and quirks. Lutris is even capable of setting up a custom Wine/Proton installation for a lot of GoG or EGS games. 2/6
