No one cared about hardware physcis...prove me wrong. There is no physcis in DX11...prove me wrong. Not the cape, but I have a feeling that you are not really looking, but try again...take notice of the side-by-side parts: http://www.youtube.com/watch?v=6GyKCM-Bpuw Going to get my grilfriend, who is no none IT person and dosn't game to watch the video too(she hasn't seen the video yet)...and ask her if she can spot the difference...as a control. It's really that this simple: For SIMD (the kind of math/calculations physics needs) GPU > CPU. That you don't understand it, isn't a valid argument.
