Download Driver For Ageia PhysX 2.5.1

Ageia released new drivers for its PhysX PPU a few days ago. The Physics Processing Unit is a PCI expansion card that can take over physics calculations from the processor. This should make games more realistic, because much more interaction with the objects in the games is possible. The drivers have been given version number 2.5.1 and the main change in this release is support for the 64-bit version of Windows XP and the first release candidate of Windows Vista. The full changelog looks like this:

Changes In 2.5.1:

• Microsoft Windows XP 64-bit now supported.
• Microsoft Windows Vista 32-bit runtime now supported.
• SDK Enhancement: Improved mesh cooking
• SDK Enhancement: Optimized narrow phase collision detection
• SDK Enhancement: Optimized broad phase collision detection
