[Camera]
fChaseCameraMaxAngle=30.0000
This controls the rotation.
Well, not quite. That's a setting that only applies to you when you have your weapon drawn and it controls... how can I put this. If you set fChaseCameraSpeed to 0, then you you can move your character 30 degrees to the right or 30 degrees to the left before the camera starts actually moving left or right. And this is only if you have your weapon drawn.
So it's not quite what I'm looking for but it is what spawned my interest in this particular option because it seems to be somewhat possible... I just need some help pointing me in the right direction. *Shrugs*
