Well, at different points of play, there will be different levels of resources used, and therefore different amounts of power. It is not a constant 80%, perhaps 80% average. I am not really sure the point of telling us this though; I would be more impressed with some new rendering technique to take the performance to a whole new level (ie. Donkey Kong Country utilized 24 bit graphics on a system that was supposed to be only capable of 16 bit graphics).
I describe myself as a little dose of toxic masculinity.
