FYI - Batman demo to download with PhysX...

Due to on the page where I originally typed it, we were still saying things like:

Wow, simple enough
It makes absolutely no sense why CPU physics wasn't optimized with this game so that all you have to do is select how you want physics done from within the game. This is a nice find no doubt but I have to question what would have been if they properly coded this game were we don't have to tweak a .ini file via physx instead of the engine itself.

and

NV can fool some of the people but not all of the people.

I believe at that time, we were proceeding on lack of info, and my statement didn't seem to hold much weight with the boys.

Now in light of some actual CPU PhysX FPS numbers surfacing, it's looking to be more correct.

With the apparent huge performance difference we are seeing, I am now thinking it is more than just an CPU optimization issue. I think it's more of a hardware limitation issue.

GPU's are just way better at PhysX. (Sorry if the 3 lines in my quote took up too much screen space.)
I will try not to let it happin again.
