Had this happen twice already, Flightbeams KDEN and default KSFO.
AIGFP set to 100%. Everything is totally fine on the taxi out and take off. Both airports swarmed with traffic waiting to depart or arrive. As soon as get into an altitude and get maybe 5NM+ from the airport, everything is coming to a crawl, literally 1-2FPS. If I turn off TC, a couple minutes later things stabilize to complete normal. I get away from the airport, turn the TC back on, no performance hit. Not used to this in FSX or P3D, usually the perf hit was on the ground. Reporting for feedback and possible suggestions to troubleshoot it.
Please post the log-files for AIGTC.
Hey Johan, I dialed the traffic sliders down to 75% and am not seeing this again. Let me set something up tomorrow and see if I can reproduce it, then attach the logs.
