HI,
All 3 settings in AAO were on line with those in your answer.
I looked at log files (*.txt.). There are 2 or 3 files per MSFS session : same number as strong stutterings. Each of these files have the same single line :
"MW: Exception received: 3 from send id 164 errloc 164".
Is this a known SimConnect error code?

What does that mean? What they should be is

• Axis to "On Change"

• Joystick high sensitivity: OFF

• MSFS SU12 LVar processing: ON

It means that i have exactly the good settings in AAO.

This morning, I disabled AAO packages by renaming Manifest.json. No strong stuttering during a 3/4 hours. flight But it looks exactly like I didn't start AOA before my MSFS session. So i gives it back, its original name before this afternoon flight. And this time I had a CTD but fortunately with not a complete freeze of the PC. I could'nt close the windows with the mouse but i can do it using Task manager to close them. And I have a log file that is stamped at the moment of the crash 14:58. :

T hope this will be able to give us some useful information.

But it looks exactly like I didn't start AOA before my MSFS session.

What does that mean? You don't need the Community packages in normal operations, AAO works just the same without them. They have a special purpose that you probably won't need anyway.

Sorry, but no, no idea. To me this looks like SimConnect has just been terminated from the other side - which is probably exactly what happened when the sim crashed. This does not tell you anything about the cause. I doubt that an AAO logfile can be of much use here anyway (because it is the sim that has problems, not AAO!). Only if there were hundreds or even thousands of exceptions in the file, that would be an indication that you did something wrong with your assignments. Unfortunately that is all theory, there is no viable way to nail this down in a deterministic way.

I still stand by what I wrote earlier. Something in your sim or in your computer does not agree with either AAO itself, its Community packages, or the .Net framework in general. That is entirely possible, which is why there is a DEMO version of AAO that everybody should try before purchase. Just look at my own devel computer - it just does not like MSFS. No matter what I tried, I never found out why that is.
