Nvidia harnesses eye-tracking to improve VR rendering efficiency
by from Techreport on (#1N33J)
Talk to any forward-looking engineer at AMD or Nvidia about VR, and they'll tell you that producing life-like scenes is going to require new approaches than the brute-force methods that we employ today with traditional monitors. One of those approaches is foveated rendering, which improves efficiency by taking advantage of the fact that we see fine detail in only a narrow range of our field of vision. Nvidia has already toyed with a similar idea with its "Multi-res Shading" approach, which renders different portions of the VR frame at different resolutions to improve efficiency.
