Hello, I have a little problem and would appreciate any help. I have Arma 2:Co on two computers. I've downloaded the MGS pack to one of them then transferred it with a usb to the other. The problem is that on one of the PCs the recoils are much weaker (feels like the standard bis ones). I also noticed when AI fired the mk 48 it had the sound of the bis m240. But when player fires the sound effect is different. Both computers have the latest patch. The only difference is that the one with the problems have both BAF and PMC. As I said, I would really appreciate some help with this.
