I'm having this issue with my whole damn playthrough, i am now almost 100hrs in and in act 3, it was tolerable on act 1 the textures would just pop in, in act 2 it was more rampant it was more often that sometimes the actual face and of my own character wouldn't even load but at least if i wait long enough it will load, but wow act 3 is absolutely horrible, every npc i have talked to have all their faces blurry including my party, and the worst thing is, this time the textures won't ever load, it just stays like that waiting to load everyone's faces are just blocks of skin with no detail.
