understanding texture streaming stats

Hello,

I am having trouble to understand the texture streaming stats, already checked the manual, but if I have understood that, then it looks like my streaming stats are not right.

In my project I only have 23 textures, all of them power of two and are marked as “streamed”. Adding up all textures “resource sizes” togerther, are less than 500 MB

In my stats say that there is 2078.33 MB of “unstreambale textures”, and the “non streaming mips” is the same number…so from where come all this textures if all my textures are “streamed”?

Also, why is the “streaming pool” already at 57% with 1712.97 MB if all my textures together are less than 500 MB?

Hope there is a good samaritan round here to help me understand this!!
thank you very much
