What is frame rate?

Frame rate refers to the number of frames that are displayed per second on a computer screen or display device. In VR, frame rate refers to the number of times the images in the headset are refreshed each second. A higher frame rate means smoother and more fluid motion, while a lower frame rate can result in blurred or choppy visuals.

Frame rate vs refresh rate

It’s important to note that frame rate is different from refresh rate. Refresh rate refers to the number of times the display device refreshes each second, including both the image and other elements such as text and icons. Frame rate specifically refers to the number of frames that are displayed per second.

How does frame rate affect VR?

In VR, frame rate plays a crucial role in creating an immersive and realistic experience. A higher frame rate allows for smoother motion and more fluid visuals, which can help to reduce motion sickness and improve the overall comfort of the user. This is particularly important for users who are prone to motion sickness or who have a low tolerance for blurred or choppy visuals.

Additionally, a higher frame rate can also lead to improved performance in VR applications that require real-time processing and responsiveness. For example, in a VR game that involves fast-paced action, a higher frame rate can help to ensure that the player’s movements are accurately tracked and responded to in real-time.

Case study: Oculus Quest 2

The Oculus Quest 2 is a popular VR headset that offers a range of technical specifications, including frame rate. The default frame rate for the Oculus Quest 2 is 90 frames per second (fps), but it can also be adjusted to lower or higher settings depending on the user’s preferences and requirements.

According to Oculus, a frame rate of 90 fps is the sweet spot for most VR users, offering a balance between smooth motion and performance requirements. However, some users may prefer a higher frame rate for certain applications or experiences, while others may opt for a lower frame rate to reduce motion sickness or improve performance on older hardware.

Expert opinion:

According to Accenture’s TQ, “Frame rate is an important factor to consider when choosing a VR headset, as it can significantly impact the user experience. A higher frame rate can lead to smoother and more realistic motion, while a lower frame rate can result in blurred or choppy visuals. Ultimately, the choice of frame rate will depend on the specific needs and preferences of the user.”
