Engineering a VR App Framerate Apparent Resolution Thermals http://gamasutra.com/blogs/BrianKehrer/20160125/264161/VR_Distortion_Correction_using_Vertex_Displacement.php

Framerate Minimum: 60 fps Ideal: 90-120 fps Most devices (screens) in current smartphone generation are limited to 60fps

Slide 24

Slide 24 text

Apparent Resolution According to Michael Abrash, for a good VR experience we need: 4K by 4K (at a 90º FOV) per eye With current gen smartphones we get 1K by 1K. MSAA helps getting a higher apparent resolution! 4xMSAA helps us achieve an apparent resolution of 4K by 4K But it’s very expensive.
