So, my impressions of all the footage we've seen of Miles so far:
Sony Conference Demo (Walking through Crowd + Bridge) - Looked incredible, and definitely up there with Demon Souls visually
Web-slinging through City GIF - Looked quite good. The City seems pretty much the same as the PS4 version, but the ray tracing on the buildings looked great, perfect use of RT
Boss Fight - Some aspects of it looked nice, but it definitely wasn't that impressive visually. Seems more in-line with what we got in the PS4 game, but perhaps some improved lighting/shadows, and better VFX?
Overall, the game looks great, like a better version of Spiderman PS4. Nothing to really complain about, that game looked amazing on PS4. Those set-piece scenes they showed at the Sony conference seemed like a fairly big step above the other footage so far though. I'm curious if we'll see more set pieces at that level of quality, or perhaps if the game will look more consistent in-person.
