Ahh, good to know.
Anything you can do about someone tilting their head? That feels like the biggest remaining immersion breaker with pre-rendered stereoscopic videos.

Need some form of RGB+D for that. I have a player for that, and sometimes it looks fantastic, but the silhouette edge artifacts can sometimes look really bad. Considering some ways of "relaxing detail around the edges".

Would we ever see a dynamic resolution that tracks where you are looking at and just lowers resolution outside the point of interest? Wouldn't that save a lot?

In the mid-90s I worked on a system that did that to maximize image processing power, CCTT: https://www.youtube.com/watch?v=HY5M1jM5ggw

The article is about doing that for pre-recorded video. For live 3D VR rendering, it's already in some game engines. Batman Arkham VR uses it (it's in the settings). More info https://www.youtube.com/watch?v=gV42w573jGA
You are off by a factor of 2 in your pixel calculation, because 5k x 5k is for a stereo pair of spheres. Equirect projections waste a fair amount, but compared to the 300% miss to get to 60 fps stereo, it isn't dominant.
