Screen tearing hasn’t been a serious issue in X11 for years now, unless you run XFCE. It’s just not an issue in Gnome or KDE.
I run Wayland+ optimus and it worked on PopOS just fine. Took a slight bit of tweaking on Universal Blue, but nothing major. Mainly it works with gaming on Bazzite but not Aurora for some bizarre reason. CUDA worked fine in all of the above.
