Asus will launch its AGEIA PhysX based card in May, The Register reports.
PhysX can not only take the burden of calculating physical effects off the main processor, but can dedicate more compute power to the task than the CPU can, Ageia said. The upshot will be worlds that work in more realistic ways: explosions can generate dust and debris; cloth can hang, tear and move when touched the way it does in the real world; smoke and fog can be wafted away as objects move through it; trees and litter can be blown by the wind; and objects can be damaged in a variety of random ways, to different extents.
However, AGEIA already has competition from ATI and NVIDIA. These two companies won't launch dedicated PPUs but they will use their SLI/CrossFire cards to do the trick.
