Thank you. I shall try this, I switched the DX12 setting on about the same time I decided to move over to Windows 11. However MSFS 2020 kept having random CTDs while loading and noticed missing ground textures at various airfields. I assumed it was Windows 11 and moved back to windows 10 only to have the same issues.
I came here and found this post and your comment, and it was “YES that’s it!” I had changed that bloody setting around the same time.
Thank you
