Bazzite desktop seems to be completely usable with a 20XX+ card. It’s Gaming Mode that boots straight into steam big picture mode that where all of the issues lies.
Cards below do suffer even on desktop though and can regularly crash due to an instability in their drivers when using wayland.
You can absolutely disable the password from sleep. And there’s different versions of bazzite. There’s the deck versions that go straight into gaming mode and the non deck ones that go to desktop. If you have one installed it’s super easy to switch to the other just from the terminal too using the command on their download and install page.
