Foveated rendering

Foveated rendering is a technique used in computer graphics, especially in the academic side of virtual reality (VR) and augmented reality (AR), to reduce frame rendering time. It renders a sharp image in the spot where a viewer is focused on a display, and fills in the periphery with low resolution.
Foveated rendering requires eye tracking to work.
It can reduce a rendering workload. It uses eye tracking hardware to determine at what point the user is looking and reduces rendering resolution farther from the user's gaze. This can be unnoticeable to the user because human peripheral vision has lower resolution than the fovea.[1]
It will likely be economical at very high display resolution and depth gadgets, such as holographic displays.
