Physics is all about how objects move and react, a challenge in the gaming environment. Based on a unique set of physics algorithms, the gaming environment is extremely compute-intensive, requiring tremendous amounts of mathematical and logical calculations supported by massive memory bandwidth. 

Kobus de Beer, ASUS product manager at Axiz says that serious gamers wanting a satisfying sense of realism and a truly captivating gaming experience need the AGEIA PhysX processor: a specialised accelerator dedicated solely to delivering rich immersive physical gaming environments.
“Until now, only limited software physics have been integrated into games. That means physics computation has been handled by the general purpose CPU, which is already burdened with the ever increasing demands of today’s advanced games including game logic and AI (artificial intelligence),” explains de Beer.
“Most of the action is limited to pre-scripted or canned animations. Even the most powerful weapons leave little more than a charred smudge on the thinnest of walls; and every opponent you take out falls in a strangely familiar way.”
De Beer says that the only way to get real physics with the scale, sophistication, fidelity and level of interactivity that dramatically alters your entertainment experience is with the ASUS AGEIA PhysX processor.
The highly specialised processor is fully engaged with handling the rendering requirements of cinematic visuals at interactive frame rates. As a result, physics in games has been limited to a few objects in a scene, one-off “effects” or visual trickery that just mimics real physics. The AGEIA PhysX Processor delivers the computing horsepower necessary to enable true, advanced physics in games.
The AGEIA PhysX Processors boasts the following features on supported games:
 * Explosions that cause dust and collateral debris;
* Characters with complex, jointed geometries for more life-like motion and interaction;
* Spectacular new weapons with incredible effects;
* Cloth that drapes and tears the way you would expect it to; and
* Dense smoke and fog that billow around objects in motion.
