KDE vs. GNOME, X.Org vs. Wayland Radeon Linux Gaming Performance With Ubuntu 18.04 LTS

[theriddick]

by fglrx I take you mean amdgpu-pro driver? since that is its current form. I'd hope your not trying to use legacy fglrx!

Michael, there is a way to run SDL2 games on Steam natively on wayland, by adding LD_PRELOAD=libSDL2-2.0.so.0
SDL_VIDEODRIVER=wayland %command% to your launch options. I would be interested in seeing native wayland vs xwayland vs x benchmarks like this, however I have noticed that some compositors don't handle native wayland fullscreen games properly.

Benchmarks are one thing and if its actually playable another. Tried cs:go again on gnome wayland session and its still terrible. Xwayland seems to run 60Hz, don't know if the fullscreen window is properly unredirected or not but there is awful input lag. Back to xorg.

Usually articles have some conclusion and now it is missing. So here you are:

Wayland is bloatware and a waste of human resources.

Running an X server on a wayland desktop is a waste of ressources" would be a better conclusion

Did you try it without Xwayland? Like seth proposed?

[Azrael5]

Are the programs used wayland compliant? Or the program used are only xorg compliant?

[oleid]

Afaik, they all use libsdl2. Hence, in theory they should work with wayland. Unless, the version of libsdl2 they are shipped with is too old.

Yea, finally, after four pages someone brought this up. These benchmarks are FUBAR because xwayland is locked to 60fps (and very jittery while gaming). What this means is that PTS is measuring frames that are discarded and never presented on the monitor while running xwayland. Try enabling V-sync and you will see that even on high refresh rate displays the frame-rate under xwayland will drop to 60fps while it should be whatever rate the display is running at.

How about actually paying some attention and maybe try actually playing some of the games instead of putting 100% trust into automated benchmarking? This issue is pretty obvious if one actually plays some games, at least on a high refresh rate display. Try something like CS:GO if you really want to make it super obvious.

The results are kind of irrelevant, since games use Xwayland. I don't think any game is supporting Wayland. It makes sense that running an Xserver on top of Wayland would be slightly slower than running Xserver alone...

It is a good troll bait though, it allows the usual forum trolls to come out of the woodwork :-)

Wayland is bloatware, see how many wayland packages is installed by dependencies while Xfce does not need them:

Most of them are probably needed for XWayland.. And if Wayland is bloatware what X11 is?
