Infamous Q&A: Only using 30% of PS3 Power

[HappySqurriel]

I'd be interested in knowing how he came to the 30% ...

I suspect it is simply the number of peak FLOPS used by this game divided by the theoritical maximum number of FLOPS the PS3 can produce. This means that the number is pretty meaningless because the achieveable maximum performance of the PS3 is far lower than its theoritical performance.
