Setting up a dedicated nVidia card just for PhysX?

[LarriusYJ]

Hi!

So I recently built my first rig with the MSI R9 280 GPU. Also, some time ago while adventuring on le interwebz I think I came across someone trying to get physx on their AMD GPU. Most people suggested the slideshow-like CPU powered physx, but someone mentioned using a dedicated nvidia card just for the physx effects while the AMD was doing the rest of the work. Now, I've realized that my old PC is just gathering dust as I'm not getting another monitor and set of peripherals any time soon. The old rig has an Asus GT 440 DirectCU (http://www.asus.com/Graphics_Cards/ENGT440_DC_SLDI1GD3/) gpu and I'm wondering if I could just throw it into my new rig (MSI Z97-G45 mobo, 2xPCIe 3.0 slots at 8x/8x when used in CFX/SLI). So can anyone here walk me trough the process of setting that up? I'm pretty sure it's not as simple as just putting the card in the second 16x slot, installing drivers and enabling physx in the game (or is it? )...

 

 

TL;DR

How to make an nVidia GPU work with physx while a more powerful AMD card does the rest simultaneously?

You can't.

I think this is a guide to do it if you are interested.

 

I don't think there is much gain though in all honesty.

You will need to find a modified "hacked" driver, or else it won't work at all. Also, you might need to find older drivers, because the current nV drivers block Cuda/PhysX when a Radeon card is installed.

it's possible, but you need hacked drivers.

Welp, that was fast. I'll see what I can do.

Thanks! Looks like I got it working following the video!
