Hey,
Whenever I take off out of an airport and climb until about a thousand feet AGL my game just absolutely dies and the frames drop to about 0.6. This isn't related to the direct to waypoint issue that people had a little while back. It's more about something loading I believe. For example, I took off from Denver today (I had a pretty chilled out scenery, not like MisterX scenery or anything) and like a minute after takeoff my game just lagged out, it didn't crash though.
I have v1.1 on the IXEG and XP10.51 on a Mac osx Yosemite.
Anything Helps,
Will
