PlayStation®VR2 Rendering Enhancements
Foveated rendering is a method of maximizing visual quality through increased resolution where the user is looking, without sacrificing performance. This is necessary for high-resolution VR displays such as in PS VR2. We have developed a method of using a PlayStation®5-specific hardware feature to allow developers to easily use foveated rendering on PS VR2.
Positional reprojection improves immersion in VR by reducing latency when the user’s head is moving in 6 degrees of freedom. This technique has been custom-built to optimally run on the PS5™ and PS VR2. Includes novel hole-filling, optimal for PS5™.

<Main features>
- Eye tracking can be used with foveated rendering to further improve quality and performance.
- PS5™ new feature allows smooth resolution changes across the display. It achieves more natural visuals on foveated rendering.
- Reprojection allows updating the image considering the latest head rotation when presenting the image on the screen. This shows a more natural point of view and improves comfort.
- Positional reprojection is an improvement over reprojection on PS VR as we can get positional tracking information at a high frequency, allowing us to update reprojection in six degrees of freedom.

<Examples of achievements>
Foveated rendering and positional reprojection will be available for PS VR2 games to use.
<Future direction>
・Foveated rendering is essential for higher-resolution virtual reality displays.
・Visual quality can be improved without sacrificing performance.
・Gaze tracking and foveated rendering are key components for a high quality, immersive, and engaging experience.
