It's a console issue in general, streaming textures etc as you run around hubs. The framerate is generally fine when you're not doing that. I actually missed the tutorial hitn about sprint early on and ended up just walking through most of the game and you don't notice it as much doing that, since you're not going faster than it's loading. Sprinting I notice it a lot though.
The problem with what you're saying and have been saying is that your argument is literally "I have no attachment because the game didn't show it to me so it's contrived"...but the game DID show it to you, you chose not to watch it, there is a big difference.
For example I live in California, I was asleep when 9-11 happened, but when I woke up it was everywhere and it had a profound effect on my day that day, was that contrived? No, I just missed it because of my own actions. It didn't just appear out of nothing, it appeared out of something I 'chose' (not really but same difference in this case) not to see.
