u can use the benchmark thingy in UT2k3, as described by Anandtech here or jus read this:
"By default the game will detect your video card and assign its internal defaults based on the capabilities of your video card to optimize the game for performance. In order to fairly compare different video cards you have to tell the engine to always use the same set of defaults which is accomplished by editing the .bat files in the X:\UT2003\Benchmark\ directory.
Add the following parameters to the statements in every one of the .bat files located in that directory:
For example, in botmatch-antalus.bat will look like this after the additions:
..\System\ut2003 dm-antalus?spectatoronly=true?numbots=12?quickstart=true -benchmark -seconds=77 -exec=..\Benchmark\Stuff\botmatchexec.txt -ini=..\\Benchmark\\Stuff\\MaxDetail.ini -userini=..\\Benchmark\\Stuff\\MaxDetailUser.ini -nosound
Remember to do this to all of the .bat files in that directory before running Benchmark.exe. "
