Using the disabled on-board graphics card as a Physics unit?

[Pattonias]

I have seen drivers that allow you to use one of a SLI cards as a physics processor. I was wondering if boards with a built in, but unused, graphics chip could be turned on and used as a physics processor. I'm not really concerned with the "why would you want to" but more the "is it possible".

Depends on the on-board chip. Some do have the option to use as a PhysX card.

You would need an onboard graphics chip that supported CUDA/OpenCL, most onboard graphics are simple chipsets (eg IntelGM950) without a lot of processing capacity and so generally don't have support for the calculation libraries.

Interesting, I will have to look more into this. Not much reliable information in this regard.
