Hi, I have a p5n-t deluxe motherboard, is it still possible to use a non nvidia card as the main gpu and a nvidia card for physx ? The next combination to be exact: 5850 as the main gpu and 8800gt to work as physx.

More about : card physx

No, you can not run 2 different video drivers at once in Windows. You have to run all your cards under the same drivers.

Yes. In Windows 7 anyway.

Interesting.... GOOD to know now. Although I have a feeling it may be a little hokey when new drivers come out and such. I dunno. Good luck with it :-)

Apparently its only vista that doesn't allow dual drivers. Although I can't speak for xp64, my 9600GSO is yet to do anything, though I haven't given it much attention yet, other than basic PnP approach: driversweeper>reinstall ATI drivers, install old pre-lockout nvidia physX drivers. Testing in Batman AA and haven't yet got PhysX running off the GSO. Gonna give it a go again in the next few days with some focus, heh.

Since I don't like to create new thread, pls allow me to join your thread to ask some similar questions.

After reading the GT 240 article I'm really interested to build my new HTPC using it since the Zotac version is looking very sexy (single slot without auxiliary power connector). In the future I'll add another powerful card whenever I need it and use it as dedicated Physx card. The questions are:
1. As a dedicated Physx card, is there any performance difference between Nvidia cards? (Eg. is GT 240 is slower than GTX 295 as a Physx card?)
2. Is there any other low-power single slot card out there that's more suitable as HTPC? Preferably Nvidia for the Physx support.
3. What happen to Havok? Is AMD already implemented it in their cards? Any software make use of it?

Thanks in advance. ^^

Didn't Nvidia start disabling PhysX support when a non-Nvidia card is detected in the system?

AFAIK newer version of Forceware don't do that anymore. I think they start from 191 and above, CMIIW though. Anyway there's still another way http://www.tomshardware.com/news/nvidia-ATI-physx-patch... b^^d

I think they might still do, but there seems to be a patch for that: link.
