Can't get physx to run on gpu on supersonic sled demo

[gazjones105]

Just upgraded to 2 msi cyclone gtx 460 (768mb) in sli. So far all is great with just one issue.

If I run the nvidia supersonic sled demo with the physx indicator on, it is showing that physx is working from the CPU. Sli is Deffo enable as everything else is working and I've checked it on gpu-z and afterburner.

I've tried sli and also tried one gpu as main card and one dedicated to physx. Which ever way I try it's the same result. Physx running on CPU.

It's only happening on supersonic sled as I've tried batman arkham asylum and that is fine.

I'm using the latest beta driver and also tried the latest certified drivers.

Is anyone running sli nvidia 400 series who is willing to try running the supersonic sled demo to see if physx is on gpu or CPU?

Many thanks.

Can confirm physx is ran on the CPU.

Thanks raven.

So is this a driver issue or is physx suppose to run on the CPU on this demo? Ive read that it use to work a few drivers ago but something has made it stop working now.

I'm on the latest betas, I would'nt worry about it, if other physx games are working OK just put it down to a bug with the drivers.
