Just checked in my own game tonight in case I haven't really noticed... I do experience this in CAS, not all hairs though. Not a trace of it in-game. I've always noticed a bit of jaggedness if I zoom out enough or turn the camera at a certain angle. Up close which is how I normally take screenshots, things are fine. It's probably because I play on a higher resolution native to my monitor so it shrinks down these kinds of things. I'm sure on 1080p it would be more noticeable for me.
I'm sorry you're so frustrated. Wish I could help. :/
