I just bought Arma 3 yesterday and decided to download it to my macbook pro 13 inch. Upon opening the training, i was faced with 45-60 fps which is not bad at all for most if not all computers. However! As soon as the first campaign mission started, i was faced with a whopping 4-5 fps. All settings are on the lowest possible, even my resolution.
Anyone know a fix? Bootcamp Arma 2 ran perfectly!
