I started ASE, then FSX, I loaded up the flight and waited ten minutes and I got the same result. Then, I closed everything, restarted ASE and unchecked visibility graduation and smoothing, started FSX and loaded up the flight and waited ten minutes and the weather was correct. This is the METAR from ASE: KJFK 281351Z 18024G33KT 0SM R04R1200FT -RA FG VV001 1514 A2972 RMK AO2 PK WND. I took screenshots of each so you could see the difference.The first one is with visibility graduation on, and the second is with it off.
