I think the demo could have been more effective if the non-realtime elements were indicated more clearly; as-is people got confused what was realtime and what was just pre-recorded. I suppose that was kinda the point, but without any sort of reveal the effect gets lost. I don't know if the console demo had the option to switch to "nanite view" at any point, or just in the "gameplay" section, if it does then I guess that would help with the situation.
