I usually use 400dpi or 800dpi. I have experimented with acceleration before. I have used sensitivity 2 cl_Mouseaccel .25 . I also have used sensitivity 2.5 cl_mouseaccelcap 5 cl_mouseaccel .12 . Any way the point is I just would like peoples feedback on acceleration in quake, if they think its bad or if you think its good. Without any accel I usually use around 2.5 sensitivity at 800 dpi.
