3D Games Performance
Unreal Tournament
This is quite an old (but still popular) game. It is known not to scale very
well with faster graphic cards, so it should run at almost the same speed in
all resolutions. 3dcenters utbench demo was used, as well as the intro-flyby
(which should be a bit less cpu limited). Almost all graphic details options
of course set to the highest setting possible. UseS3TC was set to 0.
The dri driver is the only one which shows a strong dependency at resolution.
Interestingly, when watching the flyby, the framerate didn't change much with
increasing resolution, except almost at the end of the flyby when it was
really slow - with the higher resolutions it dropped easily to below 10fps.
This is strange as the other drivers had no slowdown at all at that place -
could be some software fallback which, considering the age of this game,
would be disappointing.

That's excatly what I'm seeing for ages.
It is resolution independent.
It starts during "room entrance" and going worse when the "hero" comes up.
Fog???
Shadow?
r200, dual Athlon MP 1900+
Drops down to ~9 fps (Avg. 72 @ 640x480x24/32 on 1280x1024x24/32 desktop).
