eem just to remind u physx card is not designed to do physic calculation. its more to partical rendering and eyecandy details.

the bullet drop dont need sophiticated hardware to calculate. dice has made it simple for a single core to run.

for the bullet drop thing, i m pretty sure its the same for consoles and pc. i played it on pc and x360, and its the same, other than the its very buggy on pc.
