Thanks for the answers.
I increased the texture streaming pool size but not when I took those screenshots. It doesn´t affect the problem though. Is there any visible issue with reaching the texture streaming pool size or is just performance related? I didn´t notice any change, visually.
Thanks csimeon, I guessed it was something UV related, but didn´t know how to look for any more sources of knowledge about it.
I will take a look at your link and update the post if I manage to solve it
