I'm pretty sure it was in a recent patch, zooming in and out of a male character with muscle tone causes the textures to pop in and out. It makes it look like your character is scrawny from 10 feet out and even smaller from 20 feet out. If this is an optimizing change that's fine for rigs using lower settings. For all of those running at max settings I think we shouldn't be seeing any pop in at all. Hopefully it's just a bug.
I'm also seeing the texture rendering pop in more with tree plants and some other textures. If this was a huge open world I can see the use, but here it's a little much especially with the small areas. Very noticeable. Thanks.
