3 years (or is it 4? What is time?) on arch exclusively and I do quite a lot of gaming. It’s been great. There were a few occasions over the years where something didn’t work, while others on ProtonDB had seemingly flawless experiences, but it was always just a few minor tweaks. Much better experience than what I had on Manjaro prior to switching. Also, this is all on Wayland (sway) and even with that, it’s been great. BTW.
