This is very, very interesting; a company called Ageia has announced their plans to release a dedicated physics processor called PhysX, designed to coexist with existing GPU and CPU chips. What this means is that instead of having like a dozen physics objects in the game, you'd have something like 30,000 to 40,000 of them. Learn more details about the PhysX technology here.
GS: Can you give examples of how a game might be able to increase realism with the help of a PPU?
TS: When people talk about physics in recent games, they mostly think of Unreal Tournament 2004's vehicles or Half Life 2's dynamic objects. There, you have tens or perhaps 100 big objects interacting physically in an otherwise static environment. Knocking chairs and tables around is fun, but that's hardly the apex of physics simulation! The next steps are realistic dynamic environments, fluid simulation, large-scale particle simulation, and other very large-scale physical phenomenon. If you look at a modern action or sci-fi movie, and what's possible with the non-realtime computer graphics effects there, it's clear that major new physics innovations will be introduced into gaming as hardware performance increases 10X, 100X, and more.
