AMD for graphics, nVIDIA for physix?

Can anybody tell if an ATI 4890 can get along well with a GF 8800GT for physix? Will there be driver interference?
Did anyone try this?
Can this combination run on intel mobos? Or nForce mobos?

What? Are you saying it's not possible? Why?
I'm serious BTW..

Well, the 400 thousand posts about this over the last couple of days about how nvidia removed the possibility of doing this in thier new drivers might give it away...

damm you nvidia

To be honest i doubt physx will ever take off on a big scale, 'Havok' have a good physx engine that is used only on the CPU so their is no need for the GPU.

And using physX takes up a whole grpahx card so halves ur framerate.

In short what everyone is saying is it was possible but Nvidia shut it down quick with an update.

and while physX takes a card you can get an cheap 50-70 dollar card that will run it so that it doesn't mess with your frames.

Are you saying it was possible in the previous drivers? What drivers? I'm ready to roll back..

That is not at all how it works...

No idea. I am passing on information based on hear say as I never tried it myself. Not sure if it was added to past drivers as well or which drivers have them myself.

I would buy a physics card, problem is it's not available in my country and I was planning to use my current main GPU (8800 GT) as a physics card for my next build.
One question though: will physics codes written for nvidia GPUs (in Mirror's Edge for example) run on the old Ageia physics card without a problem?

It is possible to do, but can be a little tricky. I've done it. Read this thread for all the info you'll need. http://tinyurl.com/q9b3sg

Thats what happened on the UT3 physx demo??? Used one card for physx and one for rendering????

Orangegator,Did you try it with the 190.xx drivers?

^ IIRC they've disabled it since the 180 drivers, although it might be 190.

No, I did not. As was stated, Nvidia made it that with the newer drivers, starting with 186.xx, they disable physx if an ATI graphics card is also present.

You can dedicate which card to use for physX in a situation where you are not using SLI, but the card is not entirely used by it. For instance, a single GPU set up can use physX just fine, compared to the graphics work load the physics computation is rather negligable, though there will be somewhat of a performance hit on some rigs.

yeah but the hit would be 5-8 frames at worse. Unless you have some really weird factor going on.

Reply to darkvine

The performance hit affects slower GPUs for 2 reasons:
1-With physix enabled there'll be more particles in the scene, i.e more pixels to draw in the early rendering stages.
2-Physix computing costs some GPU cycles, the number of which increases if the GPU is slow.

Thanks NVIDIA, I'm so glad you can prevent me from using my dedicated PhysX card that I purchased before you owned the damn technology just because I have a 4870X2... And you actually expect this technology to go somewhere? Idiots...

Never actually thought about this... Surely they can't do that!!!!

Have you tried the standalone driver? http://www.nvidia.com/object/physx_9.09.0428_whql.html

Yes this can be achieved, contrary to what everyone is tellin you..... But you have a 50/50 chance of stability due to driver conflics....for the physics processor (9800), you can go to start/all programs/nvidia corp/physics properties and in there there is an option for g-force physics or ageia (enable). Make sure you have both drivers up to date and they have to be both legit from their respective websites, don't use any Beta drivers..... I have not tested this in Win 7, only in Vista and XP PRO...

On older drivers, itll work. New ones, no. Support has ended, and wont improve

Won't work if you have the newest drivers. Nvidia has it set up now that it won't even allow physX to appear in the menu if there is another card that isn't Nvidia installed.

Well it worked for me a couple of months a ago with the Nvidia 178.24 drivers...didnt know they dropped the support....

They did, was all the rage in the news last few days

Ya know, its supposed to be open, and non proprietary, this kind of action flies in the face of that.
I can understand there maybe problems, as oc said, achieving a workable solution, but owners of ATI products I think would rather find those workarounds, and put up with those problems than have nVidia cut of support for this supposedly "open" ability

I totally agree..But no problem, I keep the older versions of forceware, so I'm gonna use them, and try to have the best in the two worlds, Physix and DX 10.1 ! Thanks guys.
When I started this thread I wasn't sure this is even possible, and I was surprised everyone is talking about it and how nvidia disabled it in the new drivers..Idiots indeed. They could've increased their market share and upped the demand for their slower GPUs..
