UT2K3 even gets slightly choppy on my PC -- P4 3.06/Radeon 9700 Pro -- if I'm playing a large outdoor map with 12+ people (DM_Plunge is the worst, framerate-wise). 1600x1200, max settings, no AA. Of course, by "slightly choppy" I mean under 30 fps, which is what I assume Hydra meant as well... still totally playable. I can't wait for my G5 -- IN TRANSIT! w00t!
