Ubuntu 21.10 Radeon Gaming With KDE Plasma vs. GNOME Shell + Wayland vs. X.Org
HITMAN 2 was one of the few games where it was acting up under KDE Plasma's Wayland session.
Shadow of the Tomb Raider was also crashing under the KDE Plasma Wayland session but working fine everywhere else.
Overall though the performance was steady across the different desktop configurations on Ubuntu 21.10 with the open-source Radeon driver.
