can anyone explain why when i run a mission on fsx, the graphics are great with no freezes etc, however when i try and fly from my own town airport i get lock ups?The settings are the same

I second that ... I was asking myself the very same question.laurentC

me too, i'd like to know that, Bob

You know.... I thought it was just my imagination..... I am getting REALLY good framerates over Miami in the Triangle mission, yet when I fly there with similar weather/time conditions from the Free Flight system it's a whole lot worse.Maybe the same phenomena could explain why the demo (which is actually just a mission) was so smooth on my system in comparison to the full version.
