> Vision Pro cant sample the entire viewport 120fps Even worse than that. Each pane of glass that's blurring needs to do its own sampling of what's behind itself. That means you have to render from back to front, sampling in 3D, for each eye, to get realistic blur effects. Your vision isn't a 2D grid coming from each eye, it's conic. A line from your retina out through two equally sized panes placed in front of each other will likely pass through two different points on each pane. You'd probably need to implement this with ray tracing, to make it truly accurate, or at least convincing. And to make your device not slow to a crawl as you open more and more windows.
