No i don’t have OC enabled my CPU and GPU settings are all default.
In “normal” flight Dx12 is good. Its not the screen but the scenery that flickers and only when it has to import the very large photorealistic sceneries, when i fly over it.
I assume is has to do with the many small textures it has to load in the sim. Strange that Dx11 works well. Perhaps it is more optimized for this kind of very large scenery loading or Asobo has to do more Dx12 texture optimizing
