adjust brightness with GammaOffset=0.5 (or higher)

and if you have the 2nd UT cd with the st3c textures on it i can only suggest your to give S3TC=true a run :) (install instructions inside the opengl patch)

cheers

The problem is ATI's drivers broke gamma control several releases ago and have the problem on their support section and released a temporary fix. I suggest you go here

and get a modified utility that works better.

You also might want to check your other OpenGL settings, you can enable a number of options for extra image quality, like deatil textures. (Check explanation of the options)
