Steps to Reproduce
I am not sure, how to properly upload repro project, the link does not work.

However, the repro is super simple on vanilla 5.6

Repro

  1. Create empty level
  2. Add sphere with material which references a texture - for better visibility, I have increased scale of the sphere 10x and using 8k texture
  3. Compare requested mips with s.StreamableAssets.UseSimpleStreamableAssetManager enabled and disabled

In my case it was ~4MB vs ~47MB

This is in the editor, outside of game mode. It seems to work the same way inside of game mode. Not sure about the cooked game
