Nvidia disables PhysX when ATI card is present

vjcsmoke · May 20th, 2010, 03:36 AM

Ok so I have a couple of GTX 480 in SLI. But I recently got my 5970 back from RMA. It was replaced with a Brand new condition card! So I'm going to try something obscene and use my 5970 with a $500 physX card. ^_^

So the latest physx enabling patch is now 1.03? I'm running the 5970 on 10.4 WHQL drivers and the Nvidia on 197.55 drivers. Any complications with this setup?

Theoretically there shouldn't be any complications. But you know - life will do the verification (such as in my case). Luckily I've managed to solve it.

Houston, we may have a virus...

So today I downloaded the 1.03 physx mod linked to your signature, GenL. And I kept wondering why I didn't see the exe file after I extracted the archive. Then I notice my little antivirus alert and this is what I saw. o.O

So I don't know if someone hacked into that link and uploaded a virus or what, but I definitely can't see or run this application because my antivirus blocks it as an "infostealer" thingy. Could you look into this or point me to a place where I can download the mod without the "hidden extra"? Thanks.

vjcsmoke, both questions (about Fermi and about possible virus) are answered in FAQ.

To be precise, Fermi as a PhysX GPU was tested with 197.41 driver with a success, and no, there are no malware/viruses there (already without "hidden extra"). Just make your AV ignore it.

btw, looking at your screenshot, i suggest you read a rest of the FAQ too...

Does anyone know if it's possible to force PhysX processing on the secondary card for applications that won't do it natively?

Afaik there is no such application. They all are using a global setting from nvidia Control Panel.

Or there is a possibility that some application refuses to use GPU-PhysX at all, in this case you should delete its PhysX dlls, like in Mirror's Edge case.

I was specifically speaking of programs like Badaboom and other Nvidia demos that will only do PhysX on the rendering card. There are a few games that do this as well. For whatever reason they are ignoring the control panel settings.

Badaboom is using PhysX?

Let me guess, you were referring to nvidia demos like Particle Fluid Demo (which are using custom GL extensions only available on nvidia GPUs) and Just Cause 2 (which is using Havok)?

If you meant CUDA, then there is an answer in my post with FAQ...

A: You don't. Developers should do it. GPU-PhysX is working through CUDA, this means CUDA is not blocked by a driver.

Dude, don't be a jackass, you know what I mean. Either you can answer the question or not. If not just say so, don't be a dick about it.

There are programs that use CUDA and/or PhysX that DO NOT run in a hybrid system because they won't use the secondary card. My question was simple: is there a way around this?

I assume, from your repeated snarky responses, you don't know the answer.
