When I load up a free flight in the VC on the runway at KSEA, I initially get good FPS (around 20) - BUT if I pan the VC view sideway to see the airfield buildings, the FPS reduce to only 10. OK - that is maybe understandable - BUT when I pan back to view straight down the runway and the buildings are no longer in view, the FPS remain low at 10.I mostly fly in rural areas and haveb;t experienced this anywhere else - but it is REALLY noticeable at KSEA .Any thoughts re this?Thanks Barry

Probably because upon startup it loads and you're only viewing straight ahead, then it has to draw all the objects as you pan back and forth.
