Maybe I’m missing the point since I’m talking about the tech demo and not the movie itself, but I was both impressed and slightly concerned about what it showed off. Nanite’s real time decimation is exactly what it was premised to be - but the technique used to composite the full resolution version over the decimated one has some visual artifacts around it, especially when the player is in front of it. It made the overall image look…glitchy, I guess? Sort of like a compressed video.
In addition, I got some pretty big frame drops during the arcade shooting section.
I’ll have to play it again, but it was pretty impressive overall. I liked that they give to option see the geometry LOD change as it decimates it. All in all, it shows that the “unlimited polygon” promise is basically true. I’m betting that artifact issue will improve over time.
