As I advised in a prior post - since I have changed my PC/WINDOWS and GPU settings, I ve got no error or CTD anymore. I use MSFS “high end” settings, but reducing LOD to ca. 75… Using DX12. Got fpm about 30-60 (depending on complexity of addons).Here you see screenshots of my setings. Pls try it and give feedback if it helps! Here is a link to the video that show some of the changes Ive done. Since than Ive got no error anymore, even with PDGM B737 and many mods installed.
You see my MSFS settings at the screenshots (Nvidea Experience Software - my settings are the “Aktuell” settings - not the optimized settings, which are partly on “ultra”. Ultra settings are possible if the scenery or the addons are less complex.
