[How Do I?] Disable Texture-Streaming once and for all

Hello Guys,

i tried to disable Texture-Streaming because i can`t stand these popins/low LoD textures that you get sometimes.

Followed some Posts/Guides on how to do it but something seems to have changed.If i set all the allow.Texturestreaming entries to no,the game crashes on start.

Rising the Buffer does not seem to have an effect at all.

Can somebody please tell me how it is done or if it is impossible?

Machine i`m trying this on is i5 3570K with a gtx 970
