Here’s another DEMO, this type it’s Assassins’s Creed: Odyssey, the map of Greece.
It’s a 32768 x 32768 pixels. It would take 4 Gb of GPU memory if we were to load it as a normal texture, and the image itself, even as a PNG takes up 804 Mb, which would take a pretty long time to download for most people.
To put this into perspective, a normal 3d model might use a 2k color texture, you can fit 256 such textures into this massive 32k texture, that’s the kind of scale we’re talking about.
Although, of course, the tech is designed for much larger texture sizes in general.
I also managed to hunt down a few numerical instabilities in the shader which were causing occasional artifacts.
