This is everything I did to get the ati card to render the graphics and the nvidia card to do the gpu accelerated physx.
This is done on Windows 7 Ultimate x64 FINAL, but should work on all builds of windows 7. I haven't tested it on xp but it supposedly works on it too.
1. Have the ati card installed in the pci-e slot 1 and the nvidia card in the pci-e slot 2.
2. Have the vga, dvi or hdmi cable plugged into the ati card to the monitor, have no cord plugged into the nvidia card, it just needs to be in the slot.
3. Install the 191.07 Nvidia drivers, http://www.nvidia.com/Download/index.aspx?lang=en-us
4. Install the Physx Patch/Mod, http://www.ngohq.com/graphic-cards/1...html#post82812
6. Right click on the desktop, go to screen resolution. Under Multiple displays click extend these display's then apply. Set the Nvidia card to vga device, it will still work even though it's not plugged into the monitor. Then drag the #2 display to the bottom right corner of display #1, this way you won't be dragging programs off the screen to another screen that's not really there. LOOK AT THE PICTURES.
7. Then right click on the desktop, click nvidia control panel, then simply enable physx.
8. Download and run fluidmark (physx benchmark) to see if it's working. http://www.geeks3d.com/20090723/phys...postfx-update/
9. Enjoy your physx games
All physx games I tested work fine.
