I had done these two before and with no positive result. I’ll try other command lines later.
Today I tried the latest nVidia driver 517.48, turn off online services, stop the “Nahimic” service, remove Realtek audio console and driver, re-install the Realtek audio console and driver. After each step I’ll start the sim and made a test flight. Still got CTDs everytime, and the time that CTD occurs became within 10 mins into the flight with TAA and 5~30 mins with DLSS. The last thing I can try would be those command lines or refresh win10. If problem still exists, then maybe it’s time for me went back to P3D until the next update from MSFS.
