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.
It had an opet beta weekend prior to fully releasing as “A Realm Reborn”
