Ubuntu 20.04 GNOME X.Org vs. Wayland Session Performance Impact For Gaming
Similar to our results in recent months, switching to the GNOME Wayland based session no longer incurs a measurable performance hit for a majority of Linux games when being routed through XWayland. These games are now running about similar performance.
Including for Windows games running under Steam Play with Proton + DXVK, the performance was similar between the two desktop sessions.
