AimYaw in 2013MP

Hello people!
Does anyone know where the AimYaw optimisation code is in 2013 MP? (The code that only moves the body when he's looking beyond 45 degrees)
It used to be called

Code:

---

CHL2MPPlayerAnimState::ComputePoseParam_AimYaw

---

and setting the

Code:

---

m_bForceAimYaw

---

to true, would prevent this.
I can't seem to find where it is in 2013.
