Yes, producing two camera views at a time and at pretty high resolution. You can get away with more resolution compromises on a 2D display sitting a couple feet from your eyes versus VR displays hovering just beyond your eyes.
Clearly we just need to make longer VR headsets so that the screen can sit several feet away from your eyes! I see no potential complications or downsides with this plan.
Or wait, even better: scan lines used to allow crts to do more with less. We should really look into using CRT displays for VR headsets
