1730 Physics card question

My physics card now shows up in the device manager and PCI device with a yellow triangle. I am running new video card drivers right from Nvidia and I have selected to use the CPU as the physics card. I have dual 8800s SLI.

Have you tried re-installing the Dell PhysX driver?

cheers ...

What's going on is that the optional PhysX card in the M1730 is one made by Ageia before they were bought out by nVidia. nVidia has since changed the PhysX API to add new features that are supported by nVidia GPU drivers but not by Ageia PhysX PPUs. As a result, nVidia has discontinued support for Ageia PPUs in their PhysX drivers.

You now have a choice between installing really old nVidia PhysX drivers with Ageia PPU support but lacking newer PhysX features, or installing new nVidia PhysX drivers without Ageia PPU support.

In other words, your internal PhysX card is useless for newer PhysX games. I regret paying for the one that came with my M1730, as I've never even played any games on it that could take advantage of it. Oh well.

I reinstalled Windows and installed the Ageia card first and its showing up correctly in device manager now. Whether it works or not time will tell.

The last version of PhysX drivers that support the Ageia PhysX adapter are here: http://www.nvidia.com/object/physx_8.09.04_whql.html

If you install nVidia graphics drivers, be sure to tell the installer NOT to install PhysX drivers, or else it will uninstall the older Ageia-supported drivers and replace them with the newer PhysX drivers that only support nVidia GPU PhysX acceleration.

Actually I did tell the installer not to install the Physx driver, but in the Nvidia menu it still says its using #2 GPU for Physx. The Ageia is still in the device manager and in UT3 it allows me to select hardware physics.
