KDE Plasma 6.7 vs. GNOME Shell 50.3 vs. Xfce 4.20 On CachyOS With NVIDIA Graphics

Earlier this month I provided a look at the KDE Plasma 6.7 Wayland vs. X11 session performance for graphics/gaming on CachyOS using NVIDIA GeForce RTX 50 graphics. Since then Phoronix readers -- including some premium supporters -- requested seeing some additional desktops tested with the latest CachyOS packages. So here we are now with seeing how KDE Plasma 6.7 compared to the Wayland-only GNOME Shell 50.3 desktop as well as the X11-based Xfce 4.20 desktop on CachyOS.
