AAO 4.56 b19 causes nvlddmkm Event ID 153 CTD in MSFS 2020 -

Featured Replies

Hello,

I am using Axis and Ohs v4.56 build 19 with MSFS 2020 on a system equipped with an RTX 5080 GPU (driver 591.86).

I have identified a reproducible crash pattern:

  • With AOA active (only 2 throttle axes assigned for HondaJet HA-420 FADEC): MSFS crashes within minutes with a Windows Event ID 153 nvlddmkm error.
  • 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?

Thank you.
