From the results I've had and M4H had, it appears as though this tweak only works if you're using AF or using high detail or better, since that uses 8x AF. It's like you almost get AF for free. However, I think this tweak isn't even implementing AF correctly, so it doesn't even work. Unless someone can get screenshots showing that your AF is enabled and looks filtered compared to 0x, then there's no reason to assume this tweak will do anything, unless someone else is using something like 10x7 medium detail no AF and getting a boost.
