Dual GPUs and stereoscopic rendering

[NTMBK]

With VR headsets like the Oculus Rift not far from the market, I was wondering- has any developer experimented with a new way of rendering with dual GPUs? Given that VR requires two independent viewpoints (one for each eye), it makes sense to me that you could cleanly divide the work between two GPUs. Have any games tried this approach? Or are they all sticking with AFR?

If the developer is targeting DirectX or OpenGL it isn't really an option to do anything other than AFR. If they are going mantle then in theory they could render each eye separately on a different card although how much common calculation there is for independence from the eye I don't know.

For the normal prominent APIs I don't think its possible really, they could do other things across the two cards in terms of compute but I think you are stuck with AFR unless they announce some magic that they haven't yet talked about.
