I totally agree with the need for eliminating tearing from games (and every other application, and increasing the overall smoothness of desktop displays).
However, from the article itself, the list of regressions associated with the switch to Wayland seems to be non-negligible ; especially the lack of fast drivers for Nvidia graphic adapters, which makes it unlikely for GNU/Linux-gamers to do the switch.
Is it impossible to fix the tearing and smoothness issues of Xorg/X11?
