And other than VRR (dunno if I have it, I haven't tried) and I guess fractional scaling (but -again- I haven't tried, so dunno if it works) I get all that in xo

And other than VRR (dunno if I have it, I haven't tried) and I guess fractional scaling (but -again- I haven't tried, so dunno if it works) I get all that in xorg. Maybe you're running Gnome, which -I guess- has decided to fail to make that work on xorg?
