Planescape w/ ATI

I'm having issues with Planescape. The clock thing in the corner and character animations (eg zombies, TNO waking up) run extremely fast but actual character movement is chuggy. I have played around with all the software stuff, set cache to 1 and 32000 (works better at 1)and set the hardware acceleration to disabling direct draw/direct3d (works a little better, but still runs way too fast).What makes this even more perplexing is that I have played PST with no issues on the same pc ~6 months ago, am I forgetting something simple? Any help appreciated.
