Why does VR always have low FPS compared to playing on a regular monitor?

Question

Shouldn’t the data be processed directly to the headset instead on the monitor?

In: Technology

Answer 1

The headset has to keep track of your head motions to decide what is supposed to be rendered at any given time, on top of keeping track of what your character is doing in-game. It basically needs to keep track of both real world objects and game objects simultaneously, which requires way more number-crunching than just processing inputs and displaying the reaults to a static screen.

Answer 2

The computer has to render two video streams, one for each eye, in order to create a 3d effect.
