I'm sorry if this is a noobish question but I couldn't get a reply at the nvidia forums so I'll post it here.

I installed the newest drivers and it worked perfectly until I played batman and then the game froze and returned without physx effects. When I went to the control panel I saw this...

I normally have the 750sli set to dedicated physx but now I can't use it.

please help

Have you tried re installing them or giving the 258.69's a go?

yes I re-installed and I got the same problem. I'll report if I get any problems with the .69 update

yeah, I installed those and the physx thing disappeared. Either that means that a card has been set to dedicated physx or it's still broken.

What motherboard is that and does it have onboard graphics?

I would have thought that the 750a Sli thing on the control panel image would answer the second question :) 


It's a Zotac 750a sli

There was more than one 750a SLi motherboard so no, that didn't answer the second question as not all of them had onboard graphics.

I'm going to blame the med's for a perforated ear drum/infection so sorry about missing that, which 8 series GPU is on that board?

And I'm using a 680i SLi so what? It's the GPU that information is required for not the chipset.

That just shows the ports on the motherboard, it does not say which 8 series GPU it has. Try running CPUz, that may tell you.

I was hoping that was going to show what the onboard GPU was as the 750a SLi is a chipset not a GPU, what about GPUz? Could you try that please, it might reveal the info we seek.

the answer is always the same

Right, 4 ROPS would put it in the region of an 8400GS which is not enough to run as a PhysX card as an 8600GT or higher is required. The curiosity is, why did it work before?

I have no idea but if it is an 8400GS then it does not meet the minimum requirements.
