With all the talk about Vista and the (sorta) widespread adoption of the OS, I thought it appropriate to draw our readers attention once more to the most recent drivers for the Physx card. The drivers are WHQL certified and can be found here. The good news is, unlike Nvidia's ongoing Vista issues, these drivers should work properly with the hardware and Vista.

New PhysX Drivers v 6.10.25 were released on Friday 10-27-06. Reviewing the changes, it seems the only changes were some modifications to the installer program. As always, as there are no functionality changes, 'if it ain't broke, don't fix it' applies.

Ageia, on September 8th, released drivers for both the 64 bit version of Windows and also drivers suitable for Vista RC1. The drivers are fully WHQL compliant and support improved feature support. The drvier download page can be found here, and a PDF outlining all the changes in the driver can be found here.
