PS: The feature is called GLXVBlank.  You can disable it from  
/etc/X11/xorg.conf, although I thought it did it from somewhere else.  You  
can disable it for glxgears only like this:

  vblank_mode=0 glxgears


With VBlank I have 60 FPS on average.  Without it I have big variance, from  
1600 to 3500 FPS.
