In VR, latency is the time it takes for the system to respond to user input. Reducing latency is critical for creating a smooth and immersive VR experience.

Multithreading, prefetching, and asynchronous loading are all techniques that can be used to reduce latency in VR software by reducing the amount of time spent waiting for data or resources.

A frame rate of 90 FPS is generally considered to be the minimum for a smooth and immersive VR experience.

The performance of VR software can be affected by a variety of factors, including the hardware specifications of the VR headset, the software architecture of the VR application, and the content being rendered in the VR scene.

Foveated rendering is a technique that reduces the computational cost of rendering the entire scene by only rendering the parts of the scene that are in the user's focus. This can significantly improve the performance of VR software.

Reducing the texture resolution, decreasing the number of polygons in the scene, and using a mobile-optimized VR engine can all be used to optimize the performance of VR software on mobile devices.

A resolution of 4K is generally considered to be the minimum for a high-quality VR experience.

The visual quality of VR software can be affected by a variety of factors, including the resolution of the VR display, the graphics quality settings of the VR application, and the content being rendered in the VR scene.

Motion prediction is a technique that predicts the user's head and hand movements in order to reduce latency. This can significantly improve the responsiveness of VR software.

Increasing the texture resolution, increasing the number of polygons in the scene, and using a high-performance VR engine can all be used to optimize the performance of VR software on high-end PCs.

A field of view of 110 degrees is generally considered to be the minimum for a immersive VR experience.

The field of view of a VR headset can be affected by a variety of factors, including the size of the VR display, the shape of the VR headset, and the position of the VR headset on the user's head.

Reprojection is a technique that uses the previous frame to generate the current frame. This can significantly reduce latency and improve the responsiveness of VR software.

Reducing the texture resolution, decreasing the number of polygons in the scene, and using a low-performance VR engine can all be used to optimize the performance of VR software on low-end PCs.

A refresh rate of 90 Hz is generally considered to be the minimum for a smooth and immersive VR experience.
