It's a gaming distro built on top of Fedora Silverblue, making it stable as heck while having up-to-date official steam, and other goodies. Works on Deck too, if you want that.
No, there's also the bazzite-nvidia variant if that's the GPU you got. It's fairly easy to setup. Once you start bazizte ISO you're given a choice of the variant you want/need.
I myself run the nvidia variant on my new desktop and the OOB experience has been amazing.
