But I don"t find it useful enough. But most the real tricks used in VR and opposite to realistic and game graphics are missing.
He mentions abstraction over detailism. Good.
He mentions cheap battery powered HW, smartphones. Good.
And then he mentions some totally unimportant artefacts, fooling our perception.
But he fails to explain the importance of latency and feedback over realism, and the difference in the resolution. The problems of too slow latency, the expected lawsuits, why VR didn't make it into the consumer world in the last 25 years. Technically we were at the very same level 20 years ago already. We just didn't have smartphones.
A VR sightfield is like in a Super Cinemascope movie, like 3:1.
600x200 is perfect, as long as the tracking feedback is fast enough.
This is completely opposite to modern GPU hardware, gaming and rendering apps. All this is not needed. A hercules-like graphics card is good enough.
High resolution is only needed in the center of field, for the corners light and color information is enough.
