I recently downloaded ARMA 2 Free, and when I started it, I noticed that when I click any of the buttons in main menu, it takes about 5 seconds for game to react. Well, I didn't let it slow my gaming down, but when I went to game, I noticed that my mouse movement in game had serious lag also. E.g. when I move mouse to left, game reacts really slowly to it, and when I move mouse to right, it reacts same way. I end up in spinning around, if I have moved mouse from side to side. Does anyone have any solution for this? I don't have any mouse smoothing on.
