What Yaw pitch factor do in the options...controls.
dunno, it's never made a difference for me that I've noticed. Although I do use a joystick, if that matters somehow.

up down left right i think
Yaw = Left/Right Movement
Pitch = Up/Down Movement
As the factors are increased, the greater the sensitivity setting is multiplied.
So if your sensitivity is set on 1.0, your yaw factor is 2 and your pitch is 3, then when you move left to right, your sensitivity is 2.0, vertical movement is 3.0, etc.

ahh ok i think i have my pitch to high then lol
I cant seem to make anything different with them, last time I tried I just put them all on max and gave up... the only thing that seems to work is sensitivity for walking and swinging the tank/helo gun around.
