What would you say is a good % to put it at? And still have a large amount of traffic coming and going and on the ramp? I've brought the amount down to 18% and it still tells me to lower it. Then the airport looks like a default FSX airport, with hardly any planes there. If I go any lower then buying Traffic 360 will be a waste of money, which I don't want it to be, cause it adds too many planes.
