I've been sceptical of the 'Linux desktop' for a long time, but I recently started using Bazzite on my gaming PC and I'm super impressed. In just a few years since I last daily drove a Linux distro it's come such a long way. KDE Plasma is fast and beautiful.

So far all the games I want to play run really well, with no noticable performance difference. If anything, they feel faster, but it could be placebo because the DE is more responsive.
