I'm not sure if its Bazzite, or nVidia, or what, but any time I turn frame gen on it makes my games run like shit. This goes for every game and I have two PCs it does it on.
I also cant seem to get adaptive sync to work properly. I am on the gnome version, maybe thats related? Most of my games boot with a black screen when its turned on. V sync seems to work fine and did for me in Clair obscur too.
