You can't really "generate" a high-DPI segment. The display either has a sufficient pixel density or it doesn't. Foveated rendering let's you cheat the details you render outside the focal point, but since your eyes can move to any portion of the display, the entire display needs to have a high-enough DPI that, once your eye moves to focus on that section, the content rendered in that location will be sharp.

The limit on DPI is from the display system. Foveated rendering doesn't help.

  3840 x 2160 resolution per eye. 23 million pixels per eye, or, nearly 3x the pixels of a 4k TV with the equivalent resolution. That's roughly 3 physical sub-pixels per 1x1 "virtual pixel". As well, given the oddities of human vision and how eyes focus, they can give more subpixels to the tiny area your eye is looking at to increase fidelity

    >That's roughly 3 physical sub-pixels per 1x1 "virtual pixel". That is apples to oranges. The virtual pixels are mapped over your entire field of view where the physical pixels are mapped directly to the 2D surface itself. >they can give more subpixels to the tiny area your eye is looking at to increase fidelity Again this is a property of the display system and can not be improved by software. Additionally only one part of the lens (usually near the center) will have the highest PPD. Looking anywhere but the center will have a lower PPD.

    The Vision Pro has 23 million pixels total, or 11.5 million per eye, or 3,391 x 3,391 if square

  It does when your display has micro motion :)

Ok. Now let's wait for a display panel which can fluidly move physical pixels around to get the most of them where the user is looking!
