We've just posted the third official Ageia WHQL release of their Physics driver for the AGEIA PhysX card. AGEIA believes that games can be at far better quality once you will not only calculate pixels but also common real-world physics by a special processor. So in a way you could look at the PPU as an adon for a GPU. The new product that they will be releasing has no less than 125 million transistors on-board, which is the average transistor count of your current DX9 mid-range graphics card.

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 AGEIA PhysX processor, which was developed from day one to accelerate the highly specialized physically based simulations. And the only way for serious gamers to get true mind-blowing physics in gaming is with a PhysX Accelerator add-in card available today from leading game system vendors such as Dell, Alienware and Falcon Northwest.

This driver is certified Windows Hardware Quality Labs (WHQL) supports the Microsoft® Windows® Logo Program for hardware with the Hardware Compatibility Test (HCT) kits, test information, and data for hardware testing and driver signing. Visit the PhysX Experience ( to see exactly what AGEIA PhysX can do for your games.
