Linux gaming is absolutely incredible right now. After an essay of several months, however, I recently switched my gaming rig back to Windows 10 for three reasons alone: the multiplayer game I mainly play with my buds is one of the very, very few that won’t work on Linux due to anti-cheat shenanigans, Steam Big Screen has a persistent bug with Nvidia cards even as of 560.x, and I could never quite get Sunshine + Moonlight streaming (essential for playing games with the kids around the house) working without micro-stutters. I fully expect 2 of those to be solved within the next few months (doubtless someone more proficient with Linux could solve them in an afternoon).
Very excited for SteamOS general availability for desktops. Owning a Steam Deck has made me really appreciate an immutable OS - especially for a gaming rig, which I don’t want to spend time maintaining.
Edit: As an aside, I’ll just add that for anyone interested in streaming, Steam Remote Play has quietly gone from being an also-ran, to genuinely excellent in the last couple of years. It requires - in my case at least - a lot less tinkering than S+M and produces an extremely low-latency, high quality feed.
