GUIDE: How to Enable Physx on an Nvidia Card With an ATI Primary Card In Windows 7

I used my friends 3850 just to see if I could get it to work since I had heard people were having problems with it.

First I uninstalled all of my display drivers and ran CCleaner twice to make sure all the drivers were gone. Then I installed my friends 3850 and did not allow WIN7 pick the drivers for me.

I downloaded the ATI 8.12 drivers and installed them without a problem. I restarted when I was told to and ran Furmark just to make sure it was stable.

Then I installed the 9600GT and again canceled the WIN7 search for drivers and installed the 180.xx WHQL drivers and restarted again.

I then enabled display on the 9600GT, verified this with a secondary monitor and then restarted again just for good measure.

The last step was to go into the Physx control panel and enabled physx on the 9600GT and restarted once again.

Once I finally got all the restarts out of the way I loaded of the physx control panel again and verified that the 9600GT was the physx card, closed the control panel, and then loaded up Mirrors Edge.

I first ran through the first level without physx and everything was fine, then closed it out and restarted ME with the physx enabled and all was well.

The glass shattered like the physx demonstration and the flags blew with the physx enabled.

I am sorry that I did not get ScreenShots along the way but this guide was an afterthough that was mentioned in another thread.

Please let me know what you think of the guide and let me know if there is anything you think should be added

Thanks for the rep, I am glad to see the review might help people

Awesome, just post here or PM me and I will do anything I can to help, I just wish I had an ATI card to post pictures

Thanks, I don't think a lot of people know that WIN7 is capable of this

You install the ATI card first, then the Nvidia card and then enable it in the Physx control panel. The steps should be the same for XP although I personally didn't test XP
