As some of you know and play planet side 2 this game uses physx particles. Amazing new dynamic features is what it brings to the battlefield. Such as Turbulence particles witch follow a players turbulence think of it as somthing that could be used for smoke and, not to mention things like pieces of rocks that fly up and land on your tank bouncing and sliding off like it would happen in reallife(atleast closest to). i already know A3 uses these features (Look at what happends with smoke when a helicopter flies over) and some of the little particles. But i am missing more particles.
