unfortunately Freelook move the mouse not only the view as C2P do...
...Otherwise is a great piece of software!!
I often use the mouse to scroll the map in IL2 Pacific Fighters and for controls options screen in the game...with Freelook I must remember every time to stop Tracking by pressing a key
with my setting my head turn 90° (45°x2 left-right) with a speed 42X & 44Y in C2P
Anyway, try my .ini and set C2P to SpeedX 42 and SpeedY 44 (0 Smoothness) and Flashlight mode and tell me if you see some kind of delay.
