it is to export mfd display to other monitors via another app.
so if u don’t have another monitor to display mfd picture then u don’t need it so disable it.
Just curious– what was the default SAM/contrails/etc. duration before you upped it to 240 seconds??? The reason I’m asking is because if the default was 90-120 seconds, that would be plenty long enough for sim purposes (only my opinion, of course)
I believe it was 20 seconds, but I could be wrong. I’m aiming for lasting trails, like you’d see on a typical day.
