So for the actual reason why I went with #Bazzite: Playing games I've just barely been able to play before.
There's a few games I've been able to play, but with very low graphics and/or sluggish, which I hoped a gaming optimized distro would make work better.
So far I've tested Obduction and Quern. And also Stardew Valley, which worked fine before, so it's not in the same category, I just played it since (spoiler) the others didn't work.
