As a data point - as a longtime Linux user, I hadn't tried Linux Gaming for a very long time until recently. On a fresh machine, I installed POPos, Lutris, Steam and a few other things I forget.

I've yet to find a game that didn't work. Triple-A stuff too. I'm sure there are exceptions, but I've yet to find it. I'm guessing there's a performance hit but that's just a guess - I haven't seen it.

By far the most challenging was Assetto Corsa which took an hour of installing sequential versions of Dotnet, but even that works flawlessly now. Including a Driving wheel, pedals, etc. (Logitech 920).

Seriously -- Steam/Proton/Vulkan has come such a long way.

Instructional: Install Steam.. goto Settings.. then "Steam Play". Turn on Steam Play and install Proton (either Experimental or the Latest non-Experimental). Lutris (for GoG) will instruct you on needed Wine.
