Hello,
I am getting the same issues with Arma 2 and Arma 3, ever since I installed ESET/nod32 on my System. Constant stuttering and fluctuation with my FPS, even when I am standing stil, or just moving the camera view.
I have tried multiple things and the problems still stands. I reinstalled the Game, defragged HDD's, Stopped my over clock on my CPU and GPU. Also I can confirm, enabling Gamer Mode on ESET does not help the problem.
I will try disabling AMS, when I get home. I will update my post if the problem is fixed. (God I hope the problem will be fixed)
