Urban Terror very slow on Awesome WM, but very fast on Gnome Shell

When I play Urban Terror on Awesome Window Manager, it's very slow, even if I change it's nice value. However, when I play it on Gnome Shell it runs just fine, very smoothly and 40/50 FPS, instead of 10 FPS on Awesome WM.

Any ideas of why this happens and how I can fix it? Thank you!

awesome wm, 125 FPS here.

Got something heavy running in the background? xcompmgr? Check with htop, sort by CPU usage with 'P'.

Don't play UT, play True Combat Elite.

That's my htop.

Note: Without Chromium open, it's also very slow, which is how I usually try to play.

Is it just Urban Terror that gets different FPS on awesome and Gnome?

Don't post on the Arch forums, post somewhere pointless, worthless, time-wasting posts are appreciated.

@OP: How do you start Awesome and GNOME? What start-up apps might you have? Have you tried running Awesome within the GNOME environment, to eliminate it as the culprit?

All I suggested to the OP was to make performance comparisons between another title. Maybe you shouldn't post on the Arch forums with worthless, pointless posts.

It must have been your (deeply and well hidden) intention, as neither the grammar, nor the verbs you have used even indirectly imply that...

Nope.  I cannot parse the first comment in the way you suggest in the second comment.  ANOKNUSA was spot on.  You pressed the point, now you have heard it from a moderator.

Re: Urban Terror very slow on Awesome WM, but very fast on Gnome Shell

Well, I start apps using .xinitrc, which either have "exec awesome" or "exec ck-launch-something-which-name-i-dont-recall-now gnome-session".

I can't login now, it won't boot, but I'll post info here, I'll try other games like Sauerbraten and OpenGL demos.

Also, I don't know how to run Awesome inside Gnome (what the hell? ).

Thank you!

Re: Urban Terror very slow on Awesome WM, but very fast on Gnome Shell

I dont know well Urban Terror or Awesome WM but often enough the drop of performance between one window manager and another is due to compositing.

With the results you got I guess that Urban Terror is a full screen game and that Gnome Shell wm (think it's mutter) simply desactivates the compositing when full screen (like kwin or others) and that awesome still does the complete desktop rendering even when full screen.

I guess it may be a track.

This is exactly my thought. Do you run a compositor on top of awesomewm (such as cairo-compmgr or xcompmgr)?

I do not run a compositor and I also don't run it fullscreen, I run it in a window.
