X11 doesn’t support monitors with variable refresh rates: When using one 60hz monitor and one 144hz monitor, the shell (Gnome, KDE etc) will run at 60hz on both monitors.

Even if it is possible to use Wayland with the proprietary drivers, it’s not stable enough to be the default, for example in Fedora. Text rendering is not as good as on Windows. I don’t have any examples of this, but the text is less smooth ...
