Gaming on Linux is hit and miss, depending on the distro you use and your desktop environment. Some games should be launched with gamescope if you are using Gnome/GDM

To have HellDivers run in borderless window on Debian 14. It required me to manually compile gamescope (wasn't that difficult but Valve's instructions are out of date), and use the backports on Trixie to upgrade the kernel to 6.16, and update wireplumber and pipewire (sound was flakey on some games). Kernel 6.16 performs much better than 6.12 just generally.

All the Arkham games work perfectly. Doom Eternal has some weird latency in the mouse and aiming doesn't feel right.

I could never get my Xbox One bluetooth controller behaving with Linux. I ended buying a 8bitdo Xbox style controller which works perfectly. It is much better made than the Xbox controller and roughly the same price.
