Hey, so I recently purchased london city airport for x plane, as it is my home airport in real life, and when I loaded in the fps was really horrible. I average at 60+ fps at nearly every other airport, but for some reason i'm having fps issues at london city, it's unplayable and i'm getting maximum 15 FPS and can barely pan the camera. Could anyone have a solution for this? (also i tried deleting the preferences folder, did not help at all for me).
