Is it _trying_ to simulate a 4k display? Or is it trying to provide something different- a large panorama of 1920x1920 windows?

- Tagbert 3y agoNeither really. The VP uses a pair of 4K displays to render a high dpi section where it sense your eyes focusing. This is out of a much wider virtual display space (potentially 360deg). As your eyes and head move it shifts the image through that high resolution area. the space outside that area is rendered in a lower resolution to match your peripheral vision. This technique is called foveated rendering. People who have tried the demos say that it is a seamless experience. Moving your eyes and head around, you see things rendered at a 4K resolution but it appears that the space around you is unbounded.
- sudosysgen 3y agoThis is wrong. The eye tracking is only to reduce the computational demands, it doesn't change the DPI of the screen *at all". It's purely an optimization trick. I don't know why people keep repeating this myth. It's just not how it works. It's not moving around pixels in the physical display.
