To be honest, I have been playing with this game for a few days. I am able to improve the frame rate by setting the "NO-IPU Custom' to a negative value somewhere around -35000. It is just a workaround, since it will not make the game run the full speed. The performace depends on the stage, as far as I remember the snow stage is the worst. Feel free to find a happy medium.
Maybe some characters are more taxing to render. This game uses the highest polygon's count models in the whole series on the PS2!
