like i said b4,
the coders will then have to learn nVidia's API for physics on their cards.
and then they'll have to learn ATI's as well...

or else their physics would only work on 1 brand of cards.


having it done with the CPU is better IMO.

the main thing that takes up speed isn't the transaction between CPU to GPU, its really the transformation of physics operations for all the different particles.

for example.

you wish to move 1000 particles of dirt in an explosion.

you'll need some complex math to be preformed for every particle, so ur program will run an algorithm 1000 times to transform 1 pixel of dirt, to its next location on the screen.

it then saves those coordinates, and transfers them to the GPU to be drawn.

i guess it could be faster to do it all on the GPU, but its not worth learning 2 different Card's Libraries.

but like i said,
if a standard library like DirectX can handle physics for both cards, then i guess it would be nice.
