That (tree) LOD might be tied to latitude explains the odd behavior I have been seeing. I couldn’t figure out why the trees are always so close (where they end) in the arctic circle while they stretched on for miles over Borneo. I started to doubt my own memory lol as setting terrain detail to 200 looked like less trees than at 100 over Borneo.
It also explains this tight circle around the plane with ‘high detail’ textures in the arctic. I put that in quotes since high detail is just smoothed low res sat image terrain. Very noticeable while flying.
