I have this issue too now, except in a rover. I landed my rover from orbit on Kerbin, as I had just done 15 minutes earlier, and my frame rate plummeted. If I looked in one direction I got 15-20, another direction got 30, and looking straight up or straight down got me 60. I noticed my memory usage was also growing quite fast for just being at Kerbin not moving at all. Then it just crashed... Does anyone have any fix for this?
