Yeah heres a little snippet with the names that show up so you can see.
These are what load near the end, which are the collections.
It looks as if it definitely is loading some 4x and 2x textures, but I have no idea why.
I can't find a pattern in the loading sequence of it, since it doesn't seem consistent.
