That's actually super retarded that they moved the in game physics from the PPU to the SPU as the PPU is DESIGNED for physics and the SPU is a more versitile proccessing unit. I can only conclude that they haven't a CLUE as to what the true power of the PS3, it is impressive machinery, but I'm sure they tapped at least 20% if not 30% I'm sure most of those horrific launch games used somewhere in the 10% range.
