Summary:
Foveated Rendering support is being introduced, in order to improve the GPU performance of stereo-rendering for supported VR platforms. Performance gains will increase based on the complexity of fragment shading.
Based on the VR platform, we use either fixed foveated rendering, or gazed foveated rendering:
- In the case of Fixed Foveated Rendering, regions in the center of the screenspace benefit from higher quality.
- In the case of Gazed Foveated Rendering, eye tracking is used to determine which regions of the screenspace benefit from higher quality.
Intended Outcome/Use Case:
- By enabling Foveated Rendering on supported VR platforms, users can enjoy the higher GPU performance for all XR use cases, when using the High Definition Rendering Pipeline.
- Users can configure the intensity of Foveated Rendering, which will improve performance at the cost of reduced fidelity around the user's mid/far peripheral.
