While Microsoft's initial reveal of Project Scorpio placed heavy emphasis on 4K gaming, the huge GPU upgrade relative to the Xbox One is going to bring a big visual upgrade for the majority of us still using 1080p, too.
Windows Central has some exclusive screenshots showing Scorpio both at 4K and 1080p. The pictures aren't of real games, but rather tech demos constructed to demonstrate just what the console can handle. They were shown at a private Microsoft event.
The first demo shows a steampunk scientist in her lab and is intended to show what developers can do with minimal effort; the shaders, textures, and models are the same on both Xbox One and Project Scorpio, with only the rendering resolution improved.
