os x 10.1 and POG

Just upgraded from 10.04 to 10.1. While everything seems MUCH faster (this is on a 450 imac, dv se with 196 megs of ram), POG seems much slower. Specifically, the frame rate is so jiggy that it seems to be skipping frames all over the place, making combat completely impossible.

I'm kind of disappointed; I just registered the game, and was playing fine until I upgraded. I got in maybe 3 days of playing and now I can't go anywhere remotely tough without dying immediately, because the enemies get in 5-10 attacks before I can even highlight them. Any suggestions on how to deal with this, other than to go back to OS 10.04? Should I just play it in classic mode - it seems much faster that way.
