Download Driver For Ageia PhysX 2.5 WHQL

Ageia has released new drivers for its PhysX PPU. 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, which have been given version number 2.5, are provided with Microsoft’s WHQL certification and can be used from here are downloaded. The changelog for this release shows the following changes:

Hardware/Software Rigid Bodies

• Enhanced Rigid Body Sweep operation
• Improved sleeping object/actor operation
• Fine grain multi threading
• Greatly raised object and joint limits
• Dynamic hardware acceleration management
• Adaptive force improvements
• Improved pulley and joints force propagation

Hardware Fluids

• Improved SPH implementation
• Fluid depth smoothing
• Multiple fluid surfaces
• User-defined particles supported
• Fluid interactions with rigid body.
• Note: There are workarounds to get the same effect.

Hardware cloth

• Application control of stretching and bending resistance parameters
• Advanced two-way rigid body interaction with cloth
• Attachments to cloth
• Application controllable cloth damping and friction
• Cloth tear simulation
• Cloth pressure simulation

performance

• Increased Hardware cloth & fluids
• Faster sleeping objects processing
• Reduced CPU impact of sleeping objected
• New friction simulation
• Narrow Phase Optimization
