> 1) FPS observed is 60.2 

It's because KMS is limiting rendering to the refresh rate of your monitor to
avoid tearing.

> 2) Disable KMS and run the test again with the same resolution 
>    With UMS FPS is 118.4 

I always thought the pts demo was not as good as the anholt one for openarena -
too long and mostly not enough going on so that the average fps gets pulled up
by easy scenes that are 100-200fps.
