UT2003 has the same hidden menu that UT does. You access it by bringing down the console with the ~ key and type "preferences" (no quotes). From there you will have access to options not available in the normal menu. You can also just tweak the UT2003.ini file.
If you want to set up the game to run in max quality settings like the benches (maybe more), modify your UT2003.ini file:
