VR virtual reality in UE5 with Nanites and Lumen?

Okay, so you have tried it?

Would it be possible to make, let’s say, everything that’s more then 30 meters away, to be rendered as one picture to both eyes, and everything closer as 2?
That is, a combination of the pictures.
Or would that not save any FPS?

And do you have any comments of the other options i suggested?
Like the picture nr 2 and 3.
That is, is it possible to let the computer calculate a picture behind the eyes, and capture 2 pictures where the eyes is supposed to be?
