Traditionally hardware physics would allow greater performance over cpu physics (not always though), additional objects within the game world that allow physic interaction (e.g. more debris). Yet, I to see any actual benefit to using to hardware physics: there is no performance increase whether on my 470 or with my 8800gt as a dedicated ppu and there appears to be no increase in objects with which have physics applied to them.

Would a dev care to comment? I am wondering if there is a difference at all, I have tried messing with some of the Physx variable found in .ini files and have come to the conclusion that there is no difference between the CPU and the GPU variations - I merely want to know, because if this is the case than there is no reason for me, and possibly others, to attempt hardware physics when the end results are exactly the same.

Somewhere they did mention that by using hardware physics you will see a slight increase in fps. You will not see anything different visually.

If anyone happens to stumble on that quote, please post a link. Currently I see a decrease in frames using hardware physics...
