Cutterwood

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. : ------------------------------------- 20/05/2026 14:10:59.906 : MW: Exception received: 3 from send id 164 errloc 164 20/05/2026 14:58:23.411 : MW: Exception de HRESULT : 0xC000014B in SimConnect.

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

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?

New question to Lorby_SI. : Still no CTD but experiencing 1-second GPU drops (5-8% GPU usage only) with frozen image, 4-5 times per flight, no CPU spikes at the same time.. Two occurrences 15 seconds apart during ILS approach at 1500ft, AP+AT active, no physical input. Could the RPN script polling rate cause periodic SimConnect interruptions?

Thank you for this honnest answer. I must be lucky as with TBM 930 and Hondajet (without AOA and therefore without Fadec), I can fly everywhere in MSFS 2020.

I imported your HJET template (axes only, cancelled the button assignments as I don't have a Honeycomb Bravo). Same crash in under 2 minutes. The assignments look identical to what I had before, except for the curve shape 1.2. At this point I believe the issue is not in the configuration itself, but in AAO running alongside MSFS on an RTX 5080 (Blackwell architecture). Can you give me your opinion.

AAO minimized: still crashes. Switched to THROTTLE1/2_AXIS_SET but throttle levers are now inactive in cockpit - probably a value range issue (0-100 vs -16383/+16383)? How should AXIS_SET be configured in AAO? My settings are now : L:THROTTLE1_AXIS_SET, percent. Axis min 0 axis max 100. could you give me the good settongs ? Thanks in advance.

Hello Oliver, Thank you for your quick and detailed response. First, I will test with AAO minimized during flight. I was not doing this before, so the throttle cursors were updating continuously in the WPF window during the entire flight - which could well explain the issue. Regarding axis assignments: I am currently using THROTTLE1_SET and THROTTLE2_SET (Percent, no AXIS variant). I realize this might be a second cause: sending discrete events continuously (at every micro-movement of the physical throttle lever, including vibrations) could saturate the MSFS main thread, which is already handling physics, avionics, SimConnect and 3D rendering simultaneously. Multiplied by 2 throttles, this could cause a SimConnect overflow leading to a GPU timeout and the nvlddmkm 153 crash. I will test in this order: 1. AAO minimized, same assignments (THROTTLE1/2_SET) 2. AAO minimized, switching to THROTTLE1/2_AXIS_SET 3. Single throttle only if needed I will report back with results. Thank you again for your involvement.

Hello, I am using Axis and Ohs v4.56 build 19 with MSFS 2020, on a system with an RTX 5080 GPU (driver 591.86). I have identified a fully reproducible crash pattern: - With AAO active (only 2 throttle axes assigned, for HondaJet HA-420 FADEC): MSFS crashes within a few minutes with Windows Event ID 153 nvlddmkm. - With AAO completely closed, same flight, same aircraft, same route: zero crashes over multiple complete flights. Additional observation: AAO adds approximately +1.5ms to CPU render time when active. This disappears when AAO is closed. This strongly suggests AAO triggers a GPU driver timeout (TDR) through its SimConnect interaction, possibly specific to the RTX 5000 series. Could this be investigated for a future build? Thank you.

Sorry if I made a mistake. Which forum should I use ?

With AOA completely closed, same flight, same aircraft, same route: zero crashes over multiple full flights. AOA also adds approximately +1.5ms to CPU render time when active, which disappears when closed. This strongly suggests AOA is triggering a GPU driver timeout (TDR) through its SimConnect interaction, possibly related to RTX 5000 series specifics. Could this be investigated for a future build?
