I dunno, I was underwhelmed by TressFX. It looks better, but it's still not right, it's still "uncanny valley". It's too light and fluffy, like feathers, and it flows around in weird ways. The ponytail sticks out too far in a straight line out the back of Lara's head, like she's got her hair wound around a two inch stick.
It's like when you play Dead Space 3. You've just killed these big monsters, and then you're stomping through them, and the body parts are flying around like they have no weight, sticking to all the wrong things like they are made of tissue paper and they have stuck themselves to your trousers because of static electricity. It's totally incongruous with how you expect things to behave, and TressFX is still having that problem.
If you want to get hair right, it doesn't swing around like it's made of liquid, or fine feathers, or tiny threads. It has some weight, some structure it bounces and moves with wind and movement, but it's all in relation to the person, not some independent squirming thing.
Take a look a Cameron Diaz's hair in "Knight & Day". Seriously, it looks like they spent a lot of time on her hair. It's moving and swishing about all the time, but it's within the context of her hairstyle, not some separate thing clinging to the back of her head. The movement is limited. When she swings her head, her hair moves only so far, and then bounces back. It doesn't fly around like an independent thing moving in a wind that isn't there for anything else.
