IronMan; Ready to Roll...
Not this game but I had similar issues with GTA San Andreas. The EAX Sound was the culprit as far as I could gather; I mean small stutterings are sooo frustrating. My Geforce FX5200 was enough to play GTA @ 1024x768x32 with high quality and no AA. But the problem persisted even @ 640x480x16 no effects; everything low. Even I had Realtek onboard.
