Adding to this discussion with a solution in my case, which might point dev's in the direction of where the issue may arise for non-mod users. I started experiencing this issue when I enabled a mod that completely removes LOD. (Quentillius's "Battle Lod Remover" + "Extreme Lod Remover)I was previously using a LOD modifier (keeps LOD stages, but increases their respective draw distances) without issue. (Merwanor's Warhammer 3 LOD Distance Enhanced).Disabling all LOD mods or using one that only modifies LOD distances solved the issue for me. Running a 5080, like others here, with everything maxed out on ultra and shadows on extreme.
