"Darkest Of Days" with Physx
 

Nvidia a maker of some of the worlds fastest GPU's has come up with ways to break this normal everyday cycle of just leaving only black marks, or small holes in walls, or trees. An enviroment that interacts with the gamers is desireable. Smoke that reacts around the player as he walks through it, and loose leaves and paper that blow around and react to the envrioment are always a nice addition. With PhysX we can shoot at a wall or trees (or anything for that matter), theres more then just black marks and small holes, there are bits and peices of what we just shot at. Lets step into a world known as Physx.
