This topic is intended for both MSFS 2020 and MSFS 2024.
Additionally, it concerns NVIDIA drivers, so the information here applies to MSFS 2020, MSFS 2024, as well as Windows 10 and Windows 11.
MSFS 2020 still does not work properly with DX11. Specifically, sim continues to experience CTD during loading when using DX11 with drivers newer than version 566.36.
