GTX 480 SLI and a GTX 280 as PhysX does not work Needs a fix, Driver issue!
Hi Guys, I have a pretty interesting issue. I believe it is driver side, but I have a setup with an i7 965 EE @ 4.0 and 2 GTX 480's @ 860/1720/4120 and a GTX 280 as a Physx Card. Well my Physics score drops TREMENDOUSLY on 3D Mark Vantage when selecting Physx to be run off the GTX 280.
Comparing to it being on the GTX 480. Whats up with this? I have heard and seen many posts stating the same and all saying its software and driver related and needs to be fixed by Nvidia.

Do you guys (Nvidia) know about this? Please fix it.

Here are my two 3D Mark scores. Also just so you don't say it. I know my GTX 280 works fine. I had it running in a 3-way SLI system before I got the 480's and tested it.

Thanks.

I could be wrong but this makes partial sense if I understand it correctly. I haven't run 3D Mark Vantage before but isn't the Physx test a seperate test from the graphics? The single Geforce GTX 480 should score much higher as a Physx processor than a single Geforce GTX 280 which is what you are seeing. The idea behind using the Geforce GTX 280 as a dedicated Physx processor in an actual game is that it frees up the primary 3D graphics processor to handle 3D graphics related tasks. In a Physx only task, the graphics portion is not stressed. But if you were to play a game which has high quality graphics and support for Physx, you should see better framerates with a Geforce GTX 280 assigned as a dedicated Physx processor than if you did not have this card in your system. What is your experience with actual games?

ManuelG is 100% correct. Your cards are performing exactly as they should in Vantage. Compare the link for Vantage with Physx in my signature. Your score is higher because my 480 was only at 825/1650/2000.

Thanks guys, I did realise that after, but my one question is, the New drivers are meant for GTX 400 series only, and thus my GTX 280 is showing up using the Microsoft driver, do I have to install the GTX 280 driver or just wait for Nvidia to come out with drivers that work for all cards?

What driver version shows in device manager for the 280? I imagine you could install a newer version if necessary, but as long as you have the latest Physx package and it's working now......Why fix it if it ain't broken? I believe Nvidia is working on drivers that will integrate all cards rather than the segregated drivers for the 400 series. If it was me I'd probably wait for them.

Next week we will be providing a UDA beta driver to support both cards. I would update to that one once it becomes available.

If you're only using the 280 for PhysX, the MS driver will be fine. It's not like you need any fancy graphics tweaks or SLI support on that card, is it? If you try to install an nVidia driver onto it, it might install it to the 480s as well, which you don't want.

Thought I'd let users know that with the new Drivers, my Physx card is finally working. Batman AA shows significant increases. 2 X GTX 480 SLI with Physx on GTX480 nets me 62 avg FPS @ 2560X1600 with 16XAA/16XAF and max settings incl physx on high.

And with Physx on the GTX 280 nets me 102 FPS avg. HUGE increase, though some would say over kill.

I'm a happy camper :)

I get similar improvements. In fact, Batman runs 17% faster on Dual GTX280s with a third 280 for PhysX than it does on Triple GTX280s with PhysX running on the primary one. It's definitely better to have a dedicated PhysX card.

This is only the case with this game, so far. Others don't use PhysX heavily enough to require it.

Metro 2033 might be a second example, though. Have it on the shelf but haven't started it yet.
