The Benefits of Foveated Rendering in VR

Foveated rendering has been a thing in VR for a few years, but it's only worked typically in the center because that's where your eyes tend to look. But if you shift your eyeballs in your eye socket, moving your head, that effect starts to diminish in quality. With the PlayStation VR, they use infrared iris trackers to look where your pupils are focused and then to redirect the foveated rendering circle to that area. When you have that, you can't even tell. In the headset, you have no idea because you're not focused on it. It is a fundamentally different way of approaching displays.
