Sony's VR headset also has eye tracking.
It is a great input, but more importantly: drastically lowers the required computation with foviated rendering, i.e. rendering hires where you look, not everywhere.

Unless you’re doing at least once over 100Hz refresh rates, human eyeballs are too fast for foveated rendering. Motion to photon latency for this thing is 12ms from the presentation, which is 83Hz(so it’s 85Hz), and that’s probably for post-processing 2D warping and not 3D scene shading/rendering where foveated rendering must take place so no way that works.
They did specifically mention foveated rendering.
Also the 12ms mentioned, wasn't that from camera to screen (so the latency of both the camera sensor added to the latency of the screen) or did i misunderstand?
Now that i think about it, the eye tracking is also a camera. Hmm.
