This seems like several interesting questions in one. At least (4), (5) and (6) sound like independent questions, and maybe (2) and (3) could be a single question. I'd upvote any of those as separate questions, but all in one it seems too broad.

I know GPU prefetches textures and that's why dependent texture reads are slower, but how does it work and at what point that happens?
