Human vision is a marvel of computational efficiency

The fovea, a small part of the retina, renders content in high resolution while the rest (peripheral vision) is effectively a blur. Following nature’s blueprint, Tobii Spotlight Technology enables dynamic foveated rendering to deliver better devices and better experiences.

NVIDIA’s Variable Rate Supersampling (VRSS) solution is designed to raise image quality in VR applications running. The VRSS 2 release leverages dynamic foveated rendering powered by Tobii Spotlight Technology, which provides eye tracking information at minimal latency to the NVIDIA driver. Without any additional integration by developers or ISVs, users of VRSS-2-compatible applications will experience higher image quality around the point on which they focus in real-time.

“Eye tracking is the way to future improvements in VR rendering technology, and is the key to reducing costs and the barrier of entry for most folks.”
Venture beat logo
“This frees up GPU resources for other purposes, such as boosting frame rates or conserving power, and Tobii expects that it will be used in the future to transfer and stream data that’s been dynamically optimized for the user’s current visual focus, including over low-latency 5G networks.”
“This drastically reduces the strain on hardware processing a VR experience. As such, foveated rendering is largely considered to be one of the key components of bringing VR costs down in the future.”
