Mouse Acceleration
m_accel
m_accelexp
m_accelmax
The formula for mouse acceleration is:
(raw^m_accelexp)*m_accel
"raw" is the raw distance in pixels that you moved your mouse that frame. ^ means exponent, for example 4^2 is four squared. m_accelexp is the exponent you wish applied to the raw movement. Then, the resulting value is multiplied by m_accel, which is a sort of scalar for the acceleration. Finally, the result will never be greater then m_accelmax.
For those who do not understand the math, here it is in simpler terms: m_accelexp is how fast the mouse movement accelerates. m_accelexp 1 means that it does not accelerate at all, and m_accelexp 10 means that for every 1 pixel you move the mouse will accelerate 10. A good value for this is anywhere from 1 to 1.5, I like 1.1 or so. m_accel is sort of like a "sensitivity" value for the acceleration. m_accelmax is a cap on how many pixels you allow the mouse to accelerate. I hope that was clear.
