What is foveated rendering?
In this post, we explain foveated rendering in its two forms: dynamic and static. We describe what you can do with the technology and how it's crucial for XR.
FOVEATION TECHNOLOGY
Unlock new realities with foveation technology
Bring your XR product to the next level with foveation technology, powered by Tobii eye tracking. By tailoring graphical rendering to the user's gaze, our solution delivers remarkable efficiency and superior visual clarity, enhancing both performance and comfort.
Foveated rendering
Enhance your XR platform with foveated rendering. This technology uses eye tracking to allocate high-resolution graphics where the user is looking, optimizing GPU performance, and focusing detail where it's most needed while reducing rendering load from content in the peripheral vision.
Foveated transport
Optimize data transmission with foveated transport designed for efficient network utilization in split rendering architectures. By compressing content to reduce bandwidth in areas outside of the user’s direct gaze, this technology optimizes data transfer, crucial for maintaining high-performance streaming with minimal latency.
Benefits of foveation technology
Enhanced performance
Reduce processing loads and increase frame rates without sacrificing quality.
Improved immersion
Deliver ultra-realistic visuals precisely where the user is looking.
Cost efficiency
Maximize resources by using cost-effective hardware while still delivering a premium visual experience.
User comfort
Ensure a flawless user experience by avoiding nausea and discomfort which can be caused by VR headsets.
Partners in the XR ecosystem
NVIDIA VRSS 2
NVIDIA’s Variable Rate Supersampling (VRSS) solution is designed to raise image quality using foveation technologies. VRSS 2 uses Tobii eye tracking information delivered by a foveated gaze signal with minimal overhead to the NVIDIA driver.
This architecture ensures that VRSS-2-compatible applications will reap the benefits of dynamic foveated rendering without additional integration.
Tech reviews
It saves processing power and works surprisingly well, and it's exactly what the next wave of VR headsets will lean on to create higher-res graphics on small headsets with limited battery life.
CNET
Foveated rendering relies on eye tracking. In fact, that eye tracking needs to be essentially perfect. Otherwise, there would be distracting delays in detail when looking around. Not all foveated rendering solutions are created equal. The better the eye tracking, the more gains can be found in rendering efficiencies.
Upload VR
Foveated rendering on PS VR2 can bring a massive reduction in GPU usage while producing the same perceptual quality – and, combined with eye tracking technology, the performance gains are even better...We’ve also seen gains up to 3.6x faster when foveated rendering is combined with eye tracking.
