I started on Arma 3 several weeks ago, but didn't get it finished. It was put a little on hold and I actually picked up the thread again yesterday right before your post I need to re-visit the game at a some point though, as the calculations are not perfect. It might not be noticable, but it bugs me The problem is that the engine in Arma 3 is not consistent in how far 1 count moves the crosshair. I don't know it this is a random element they put it on purpose or if it's bad programming, but it makes exact calculations impossible since the movement is a little different each time. This is not acceleration btw, as that never affects just 1 count, only when many comes in a series.
