Cause of violent wind changes?

Yep, that's right PITMN. I am most interested in your experience along the BKE-MLD segment of the route. That is where I am having violent shifts and eventually a crash.Kylehttp://www.precisionmanuals.com/images/forum/747400.jpg

Just passing MLD now. Getting spurious wind fluctuations that bounces my IAS around just a little bit, but nothing terible. No CTD yet! Did you modify your boot.ini with the userva switch? If not running SP2/Accel, did you use the hack to set large_address_aware on the fsx.exe file? You might be running into OOOM conditions. I am also running GEX, UTX, FSG, along with the other stuff I mentioned.

I am using Vista 64 bit so the userva is not necessary any more. OS sees all 4GB of RAM. I am running Acceleration, so the large_address_aware flag is set, I even double checked with CFF Explorer. I just completed 2 flights with smoothing off, and no crash. I will try again tomorrow with smoothing on again. The crash that I get is a exception in the ntdll.dll module, and they didn't start popping up until last week, when I started testing the new betas. This is getting really frustrating. I am also using GEX, UTX, FSG and FEX. One thing you didn't mention in your post is if you are using the wind smoothing in ASX? I did not like the way it set the winds, so I have turned it off. I think Dan Downs isn't using it as well. I was getting some strange winds with it on, like jetstreams going east to west, plus I didn't like the way it changed my destination airport surface winds.Kylehttp://www.precisionmanuals.com/images/forum/747400.jpg
