sorry but this is b.s.

you actually tried a physx game on an ati card? it doesnt make a single diffrence when you turn off hardware accerelation. Most games doesnt even give you the option to "turn on" hardware accel. and they work "EXACTLY" same on both cars, actually when hw acc is turned off, gfx card becomes irrevelant it even runs same on a SiS card.

Many AAA titles use physx, if there were such thing, wouldnt you think their sales dept. think twice before using physx?

Even if that's true, the thing would be a plus for Nvidia cards but not a minus for Ati. Newton or other physics libraries give no + to any card.
