Just yesterday I was flying a chopper around Chicago and though I'd practise my hovering by flying near the blimb and holding position. To my disarray the blimb disappeared altogether before I could get very close!This morning I flew a chopper again around San Fransisco and when I approached one of the fixed scenery buildings it also disappeared!I never noticed this before. Is there a fix of any sort for it?Thanks in advance.James

I have had the same thing happen along the Seattle waterfront. I think this is the result of the system having trouble maintaining the frame rate and FS turning scenery detail down to maintain the frame rate.
