Whenever I enter a vehicle and switch to first person view the sound becomes aweful and I have fps drops. Its unplayable this way. Problem occurs if Arma is using my headset(7.1 usb). I did some research and its a known problem for many players and probably for the devs too. I tried using the windows drivers for my headset and it fixed the bug but thats no solution to the problem as Im missing many feature such as surround sound. Fix it please. Its sad that it hasnt been fixed yet. Its a known problem for years...
