Benefits
VRWorks enhances advanced VR performance by increasing application rendering efficiency and image quality through the use of variable-rate shading and foveated rendering. It offers easy integration and unlimited configurability, thanks to versatile tools and extensive support for multiple graphics APIs, enabling developers to deliver superior VR experiences effortlessly. Additionally, optimized HMD support exposes headset manufacturers to the latest NVIDIA hardware technologies via a plug-and-play collection of APIs, resulting in more performant, immersive, and responsive virtual reality environments.
Variable Rate Shading
Increase rendering performance and quality by applying a varying amount of processing power to different areas of the image. Variable Rate Shading (VRS) is an easy to implement rendering technique enabled by Turing GPUs. With VRS, single-pixel shading operations can be applied to a block of pixels, allowing applications to effectively vary the shading rate in different areas of the screen. VRS can be used to render more efficiently in VR by rendering to a buffer that closely approximates the lens corrected image that is output to the headset display. VRS can also be coupled with eye-tracking to maximize quality in the foveated region.
VRSS
Foveated rendering improves VR image quality by sampling select regions of the HMD screen at a higher shading rate. The latest version of VRSS (Variable Rate Supersampling) supports gaze tracking by integrating eye-tracking technology to dynamically change foveated regions based on where the user looks. VRSS is a zero-coding solution for application developers–all the work is done through NVIDIA drivers and the end user simply turns on VRSS in the NVIDIA Control Panel. HMD manufacturers can integrate their eye tracking run-time to take advantage of these features.

Multi-View Rendering
By rendering four projection centers, Multi-View Rendering (MVR) can power canted HMDs (non-coplanar displays) enabling extremely wide fields of view and novel display configurations. MVR is a feature in Turing GPUs that expands upon Single Pass Stereo, increasing the number of projection views for a single rendering pass from two to four. All four of the views available in a single pass are now position-independent and can shift along any axis in the projective space.
VR SLI
VR SLI provides increased performance for virtual reality apps where multiple GPUs can be assigned a specific eye to dramatically accelerate stereo rendering. With the GPU affinity API, VR SLI allows scaling for systems with more than 2 GPUs.
