1080p vs 60fps

4k is useless and way too much required rendering.

We need to go 1080p vR

Except for life like VR 4K is still too low.
1080p standard is suited for a 30 degree field of view (SMPTE 30), while with VR you want to have at least an 80 degree field of view, or even upto 120 degrees. (Occulus rift uses a 110 degree field of view) So if you want VR at 1080p quality, you need 8K per eye.

You can ease the rendering load if you have reliable pupil tracking, the human eye only sees sharp in a 6 degree field of view, the rest of your 120 degree visual field is peripheral vision which is more sensitive to motion and flicker but has very poor resolution. So if you render in the highest resolution in a 10 degree field of view with 60fps, and render the rest in low resolution with 240fps, you probably get pretty far in tricking the brain that's it's close to real life. (Assuming the pupil tracking doesn't have significant lag...)

My lips are sealed, but I can post links all I want.
