Well for one XP is DX9 Vista obviously DX10.
As for my experience with UT3, I was getting some pretty crappy framerates when I finally realized I had everything set to max quality in CCC so it was trying to run @ 24xAA. Set everything in there to application controlled, and the others to quality. I bet your FPS will jump up.
