ive recently brought arma 3 when i run on high settings im at around 25-50 fps depending on the game mode, i have an fx 6300, 8gb ddr3 ram and a gtx 1060 6gb.
could it be my CPU which is slowing me down and would an i5 7400 allow me to achieve 60 fps. as some of my friends with worse specs than mine run the game at 60 fps high settings
