After decades of listening about Central Processing Units, years of listening about Graphic Processing Units and millimoments of listening about audio processing units, it is time to learn the new term. It's time to start talking about physics processing units (PPUs).
The answer is actually an add in card with either PCI Express or a PCI interface with up to 128MB of dedicated GDDR 3 memory that will take over all physics in the games. We saw some cool demos done in software on a laptop of what this card can do. It can operate with 32000 particles/rigid bodies or should I say bones? [You should, Fudo, you should. Ed.] When we talk about fluids, such cards can handle up to 50000 rigid bones. A CPU can do a couple hundred at the most.
We saw some cool demos where the company demonstrated "liquid fluids" with many "bones" and you can see the "lava" and "water" stimulations that look much better than ever before. It looks more real and much more alive.
Such cards can give some life to collision detection and can for example make a character go through grass and move every single grass while walking, adding a higher lever of realism into the scene than ever before. Looks cool I have to say. What need for grass?
We also saw some liquid simulations, where you could see blood spilled more realistically than ever before. It's especially good when you blow up a house into the smallest infinitesimal pieces, or bricks and mortar as the INQ calls them. It actually looks out of this world. I cannot imagine this in a war game. It will blow your minds.
Why go outside?
Age of physics processing units dawns
