As mentioned on one of my previous threads, I installed OpenLC North America a few days ago, but haven't had much of a chance to fly since then. I did test it by slewing around KORD a few times and everything seemed fine. However, last night I did a full flight out of KSEA and had a G2D.dll CTD about 10 seconds after takeoff.
One thing to note is that, when I started the flight at KSEA, the scenery load time was also immensely long. Easily 5 times its usual duration. I don't have any KSEA custom scenery or airports, literally only FTX Global and OpenLC NA. Loading at KORD results in a short load time and no crashes. Seems the issue is centered around the northwest US maybe?
Before OpenLC NA, I had no crashes in the area.
