I use btwOS btw doesn’t roll off the tongue tho

Firstly disclaimer, instance url. In my limited experience (on various flavours of Arch, including vanilla), most steam games I’ve tried have worked with minimal tweaking. FF XIV (running outside of steam) also runs with only minimal hickups (occasionally stays on a black screen and has to be restarted on my system).

I’ve had no issues so far from nvidia’s proprietary drivers, I’ve yet to try the open source alternative.

At the end of the day, how much of a hassle it is, depends entirely on the games you intend to play. For me, I ended up setting up a windows VM with GPU passthrough for the more stubborn games, though so far I’ve only needed it for one.

TL;DR: YMMV, but it’s far better than even a few years ago.
