Gaming performance is actually better on Wayland.

*on some games…

Did you read your own source? They covered:

Cyberpunk2077 (slight advantage to Wayland on AMD, slight advantage to X.Org on Nvidia)
DiRT Rally 2.0 ( X.Org is clear winner…)
F1 22 (Slight advantage to Wayland on AMD, clear advantage to X.Org on Nvidia)
GTA V (Clear advantage to X.Org Nvidia only… Since AMD was having driver issues with this game)
Hitman 3 (Slight advantage to Wayland on AMD, clear advantage to X.Org on Nvidia)
Metro Last Light Redux (Slight advantage to Wayland on AMD, clear advantage to X.Org on Nvidia)
Shadow of the Tomb Raider (Slight advantage to Wayland on AMD, clear advantage to X.Org on Nvidia)
Total War: Three Kingdoms (Slight advantage to Wayland on AMD, clear advantage to X.Org on Nvidia)
X-Plane 12 (Slight advantage to Wayland on AMD, clear advantage to X.Org on Nvidia)
Quake 2 RTX (slight advantage to Wayland on AMD, slight advantage to X.Org on Nvidia)

Where “slight” is within a few frames… let’s call it 0-5 frames… and clear advantage is ~10 frames+…

It’s clear that X.org is better overall. It’s capable of giving the user more options in hardware with less bullshit.
