I'm posting this here to help clarify some things i keep seeing around the place about PhysX - there seems to be some large misconceptions and misunderstandings relating to it.
PhysX is a Physics engine made by Ageia, and bought out by Nvidia. It supports software mode, and hardware acceleration.
In pretty much every thread i see about Nvidia vs ATI (so, anything involving video cards really) someone ALWAYS mentions PhysX, either that Nvidia is superior for having it, or that ATI cant do it (or can with a second Nvidia card) and various other things.
Well, heres the part no one seems to mention: How many games actually USE it?
This Wikipedia page looks impressive - check out all those titles, even a few big names in there (Batman AA, Borderlands, dragon age, etc).
Ok cool, so hurry up Mussels and get to the point.
The point is which of those titles support HARDWARE acceleration - as in, which games actually benefit from having an Nvidia GPU.
Hmmm, 15 games. Lets count the big titles: Unreal tournament 3, Mirrors edge, Batman AA and GRAW 2. Ummm, yeah. Less than impressive.
When you consider that in those games PhysX pretty much amounts for non-interactive 'looks only' physics effects (waving cloth, or random added debris that hurts FPS and not helps) PhysX starts to lose its shine. In fact the only reason it seems to have taken off is a program not listed, and thats 3Dmark vantage. Vantage uses PhysX to calcluate the CPU score, so Nvidia users get a massively higher CPU score in the program.
So after my wall of text, whats the point? Hardware PhysX is basically worthless, do NOT base any purchases based on hardware physX support.
P.S - this is not an nvidia bashing thread, which many of these turn into. Should this happen i'll just lock the thread - at least then people can still read the truth about PhysX without having to get yelled at by fanbois from both sides of the fence.
