The GPU is responsible for rendering the 3D images that are displayed in the headset, creating a sense of immersion for the user.

The resolution of a VR headset's display is determined by the number of pixels that make up the image. A higher resolution display will provide a sharper and more detailed image.

The refresh rate of a VR headset's display is measured in hertz (Hz) and refers to the number of times per second that the display updates its image. A higher refresh rate will reduce motion blur and make the VR experience more immersive.

The field of view (FOV) of a VR headset is the angle of view that the headset provides to the user. A wider FOV will provide a more immersive experience, but it can also be more demanding on the headset's hardware.

Positional tracking in a VR headset is used to track the user's head and hand movements, allowing them to interact with the virtual environment in a natural way.

The latency of a VR headset is the time it takes for the headset to display an image after it has been generated by the GPU. A higher processing power will reduce latency and make the VR experience more responsive.

High latency in a VR headset can cause motion sickness and discomfort, reduce the immersion of the experience, and make it more difficult to control.

Increasing the processing power of the headset is a common method for reducing latency, as it allows the headset to generate images more quickly.

Haptics in a VR headset are used to provide physical feedback to the user, such as vibrations or force feedback, to enhance the immersion of the VR experience.

The overall performance of a VR headset is determined by a combination of factors, including the graphics processing unit (GPU), the processing power of the headset, and the latency of the headset.

A refresh rate of 90 Hz is generally considered to be the minimum recommended refresh rate for a VR headset to minimize motion sickness.

Organic light-emitting diode (OLED) displays are commonly used in VR headsets due to their high resolution, wide color gamut, and fast response times.

Foveated rendering is a technique used in VR headsets to reduce the computational cost of rendering the entire scene by focusing on the area of the scene that the user is currently looking at.

Increasing the processing power of the headset is a common method for reducing latency, as it allows the headset to generate images more quickly.

Eye tracking in VR headsets is used to track the user's eye movements, allowing the headset to adjust the image accordingly and provide a more immersive experience.
