How to disable mouse accleration & mouse lag in ARMA 2?

[xtobix]

Is it possible to disable the mouse accleration and mouse lag in arma 2? (I've read that mouse lag could be caused by using vsync.. Normally I play all my games without vsync.. but in ARMA 2 there seems to be no option to disable it.)
I use a logitech MX518 mouse with setpoint and in my settings mouse accleration is turned off.
My system:
Intel Core i5 CPU 750 @ 2.67GHz 2.66GHz
4,00 GB RAM
64Bit Windows 7
Radeon 5850 video card (DirectX 11)

Hope somebody can help me, because that mouse accleration is REALLY disturbing.. as well as the lag..

mouse smoothing in game options > controls > right side
slider to the left


then in arma2oa.cfg change this line
GPU_MaxFramesAhead=1000;
or any other value if you altered it already

to value
GPU_MaxFramesAhead=1;

yea.. lag is fixed now..
but what about that mouse accleration? is it disabled now or do these settings only disable vsync and mouse smoothing?
thanks for your help.
