I spent many hours playing this on an Athlon 1.2 with a GeForce 2MX about 6 months ago when it came out for the PC and I can say one thing..I'm not excited at all at how it performs on my MDD 867 with 1GB Ram, Radeon 8500, 10.2.6 and no other processes running on the background. Had this been compatible with OS9 i believe it would've been at least 30% faster (in terms of the min sustained fps which account for the chopiness of the game at times), but hey that's another issue. Overall I'm glad that it came out, but I don't see many people excited especially with the gameplay which has deviated from the original UT gameplay by much too much and I can't say for the best either.
