Fwiw, I read an article the other day that stated that dual-GPU cards are likely going to be ideal for this. I'm not a graphics hacker, but the gist was that a lot of modern rendering techniques had broken the ability to split workload via alternate frame rendering. However, since each VR eye can essentially be independently run as its own pipeline, they'd see a much more ideal speedup in "same scene, two eyes" workloads.
