VR is a technology with a sense of immersion that permits users to experience a virtual environment as if it were real. To be able to do this, your computer needs sufficient processing power since it must render and present 3D models in real time. So is VR GPU or CPU intensive?

VR requires both GPU and CPU-intensive hardware, with each element playing an essential role in its performance.

The GPU (Graphics Processing Unit) renders 3D graphics displayed on the headset’s screen, while the CPU (Central Processing Unit) manages all aspects of system operation, such as handling VR software, tracking user movements, and controlling peripherals.

VR requires the GPU to render a large number of polygons at high frame rates in order to deliver an immersive experience.

To accommodate more polygons, your GPU must be sufficiently powerful. Furthermore, display resolution affects the workload on the GPU; higher resolutions necessitate more processing power to render an identical scene.

The CPU is essential for VR, as it must oversee the overall performance of the system. This involves tracking user movements, managing VR software, and controlling peripherals like controllers and sensors.

A powerful CPU is especially essential when developing applications requiring extensive data processing, such as real-time physics simulations or complex AI algorithms.

The CPU is responsible for running software, processing input from various sensors, and other tasks essential to a VR experience, such as audio processing and physics simulations. The more complex a VR application becomes, the more CPU resources it will need.

Therefore, both the GPU and CPU are essential in providing a superior VR experience. However, it is mostly the graphics card that is doing the hard work. And you can see that in the requirements, with the Index just requiring a dual-core CPU but a higher GPU.

As such you want a powerful card to be able to run the higher resolutions in the headset. As well as accommodating the higher refresh rates needed for a better experience.
