Mirror's edge has presented some problems with this method. But that's what this thread is about.

Read the OP and you'll see how it's done.

EDIT: Go to your User CP at the top of the page, and on the left hand collum go to "Add System" and add in your system specs.

I doubt it's the PPU, but the settings you're using in game that are too much for your GPU.

Mirrors edge takes a little more tweaking, I had the same problem with both my NV/NV and ATI/NV set up.
What worked for me, link.
For some reason physx keeps running on the cpu until you delete those files.

Got my 8800GT installed with my 4890, followed the guide, Have PhysX check box enabled.

Running fluid mark with or without it make no difference though
post #265 of 1230
Just run a PhysX demo with MSI afterburner OSD enabled showing GPU load and there's no load at all on the 8800GT

Run fluidmark, tells you right at the top if you're using hardware or software physx.

Also you'll have to bump the clock speed up on your ppu a little before msi will give readings.

I got it working

Just install all the PhysX games you want, uninstall PhysX drivers from the control panel and then install an older version + patch and job done

And what you meen bump clocks up before MSI will give readings?

Never mind, got it reading, 8800GT only loads max at 35%, What a waste

right i cant get this to work properly

5770 primary, but shows as gpu 2 in msi and everest

8800gs physx is enabled, fluidmark shows hardware physx

just casue 2 starts with a really odd resolution and i cant correct it

also 3d mark doesnt show any improvements either, i always seem to get ~16k for my cpu weather Physx is hardware or software

JC2 does not use physx, JC2 makes Cuda calls and is forced to run on the Cuda capable card.
You'll have to disable your NV card to play JC2.
