[Console Commands]
These commands can be adjusted before or during game via the developer's console ([~] key).

m_filter [0|1] – This would be the console equivalent of the Mouse Filter command. 0 = Off, 1 = On. Recommended: 0 (Off)

m_forward [x] – Adjusts the sensitivity of forward and backwards mouse movement.
Recommended: Default

m_pitch [x] – Adjusts the sensitivity of up and down mouse movements.
Recommended: Default

m_side [x] – Adjusts the sensitivity of sideways mouse movement.
Recommended: Default

m_yaw [x] – Adjusts the sensitivity of turning left and right with the mouse.
Recommended: Default

sensitivity [x] – The console equivalent of “Mouse sensitivity.” This is the most effective method for changing sensitivity as not only can you include decimal values, but you can also adjust it faster on the fly.
Recommended: Pure Preference

zoom_sensitivity_ratio [x] – Temporarily adjusts the sensitivity of your crosshair upon zooming dependent on the ratio set. What does that mean? Let us say you have an in-game sensitivity of 4, and a zoom_sensitivity_ratio of 0.5. With this ratio your mouse speed will be cut in half (0.5), changing it to a sensitivity of 2 while zooming.
