After spending some time with this demo, I'm even less impressed than I was yesterday. The tech demo looks okay and frankly, apart from the density, it's not revolutionary at all. I think developers have gotten good at faking it with several tricks(Baked GI, High Res Cubemaps, Good SSR) that when you get real thing, it fails to impress.
The resolution, framerate, TAA ghosting, animations and physics ranged from average to awful. As a whole package, its at best a step sideways from what we've seen so far and in some categories, it's a clear regression. I was more impressed by the showing of ARC Raiders than I was of this tech demo.
At the end of the day, most consumers don't care if you're using real time GI or Baked GI, SSR or RT, etc. They care about the results and frankly, after all the hype from Geoff, this was thoroughly unimpressive.
