Ah, I see what you mean FT.
I think I'm vaguely aware of something going on but it doesn't seem to effect me.
Probably because there's less going on between my ears.......
GUI background mute? I haven't got that but I'm not aware of any background noises when reading the brief - apart from the sound of people coughing, farting, laughing, etc......
I'm leaving the F/A18 alone for now as I've got plenty of DCS to get my head round but a couple of questions - if anyone knows the answer - will this be compatible with the Tomcat and if you don't own it will you still be able to land on it in a multiplayer mission?
