Setting up PhysX on ATI
Getting PhysX up and running is really quite an easy task; it's just that there's some misinformation out there which might make it a little confusing. The first thing we do is install both our cards, then we install the drivers, which in our case are the Catalyst 10.5 and the ForceWare 257.15 releases.
Once that's done, we fire up GPU-Z and have a look at the cards. If you look at the bottom you'll see PhysX isn't ticked. That means it's not working. Now, if you've read Windows 7 information regarding this you'll have heard that you don't need to set up a fake adapter and extend your desktop. Well, in this case that isn't true.
So what we do is right click our desktop and go to screen resolutions.
Once that's done we hit Detect, move over to the monitor that shows as connected to the NVIDIA card and force the monitor via VGA. Hit apply and you'll now see your two monitors. What you then do is head down to Multiple Displays and extend the desktop.
Once that's done we fire up GPU-Z and as you can now see, PhysX is ticked. Now that that's working, let's get stuck into the benchmarks.
