Turning off Texture streaming?

Hello all,
I have a simple question. Does turning off texture streaming via console (r.TextureStreaming 0) affect my project after it has been cooked?
If yes than how?
What tradeoffs can would I have if I limit my texture pool size to 1000mb and turn off texture streaming?

The reason I am worried about is cause
the Streaming stats indicate over 2000mb usage under the non streaming Mips tab. I have read a whole bunch of wiki and question/answers. I am still unsure which tradeoff would work best for me… especially cause it is a VR project.

I’d like to know an answer to this as well.
