KDE/GNOME Wayland vs. X.Org Radeon Linux Gaming Performance
The HITMAN 2 benchmark under Steam Play remains quite problematic with KDE/KWin with various issues but behaved well with the other desktops and enjoyed leading performance under GNOME's Mutter Wayland compositor.
There was little difference with Valve's Left 4 Dead 2 game.
Shadow of the Tomb Raider was running great with the GNOME Wayland session but crashed under the KDE Plasma Wayland session.
