But I’ve spent most of the time tweaking and setting up and downloading stuff rather than actually playing. Games seem to work really well. Not doing benchmarking but I really like how stable the framerate is when frame cap is in place. So far everything I’ve tried was absolutely buttery smooth.
I used Ubuntu before Arch, and I would say the opposite is true. Ubuntu disabled all the repos you had to add just to get up to date software, and would often just fall over with every version update.
Anyone that wants to game on Linux should stay away from Ubuntu IMHO, unless you like playing old games and a system you cannot update without fear of having to reinstall the whole OS like Windows back in the day.
