I´m too having problems almost everytime I arrive at KORD. It happens in short flights, such as departing from Las Vegas, Orlando and so on. The plane I use isn´t known as a memory hog, and in fact this problem doesn´t happen when arriving at other large airports, such as FSDT´s New York Kennedy and Las Vegas, even after a long haul (lots of hours flying). I´ve tried to change the priority of the sceneries, but to no avail.
Rgds,
