The vertical blank interrupt is most likely using the blitter a lot and waiting for it to finish. The blitter is no faster on an 030 (in fact the code can run so fast that it ends up waiting a lot more eating up precious DMA cycles), so you will generally not see much of an improvement.

If Ruff'n'Tumble ran at a constant 25fps I doubt it would appear as jerky as it does, hence it's probably dropping a frame regularly or scrolling too many pixels at slow screen updates.
