Fedora 24 Alpha X.Org vs. (X)Wayland Gaming Tests
I did run some quick game tests this afternoon of Fedora 24 Alpha when running on the X.Org Server (default) and then when running GNOME on Wayland where the games end up getting piped through XWayland. For your viewing pleasure, here are those quick results.
A Radeon R9 290 graphics card was used for testing the two display options on Fedora 24. Fedora 24 currently has the Linux 4.5 kernel, GNOME Shell 3.20.0, and Mesa 11.2.0-devel as the important components worth mentioning.
The performance impact was small of the overhead of dealing with XWayland on Fedora 24 atop GNOME 3.20.
