Whilst checking out a reasonably complicated scenery I took a look at the factors within my control that might impact on framerates. One had a far greater effect than the others, the Airline Traffic Density slider in FSX. It won't be helped by the fact that some of my AI aircraft are flyable, with a decent appearance. Like the Flybe Dash 8 Q400, the Monarch B757 etc. Is there anything I can do to these models to reduce their effect on framerates, when used as AI?
