"According to an announcement made on Thursday, Sony entered a 'strategic licensing agreement' with Ageia, and fabless chip developer that developed the 'PhysX' SDK. PhysX is a physics chip that is designed to aid the graphics processor in darwing realistic graphics on a screen. According to its developer, the device can simulate thousands of interacting fragments, which could create a greater illusion of reality. The behavior of 40,000 to 50,000 particles can be simulated per screen allowing the display of disintegrating walls, gelatinous characters, windswept hair, loose flowing clothing, or realistic display of damage in car racing games."
