I have the same problem with Photogrammetry in Paris and London looks horrible like an abandoned town after a nuclear strike. Graphics setting set to standard HIGH, all data on, pretty dissapointing.
But while flying in eg. EKCH Copenhagen photogrammetry is fine and pretty awesome.
This happened to London efter the world update 3 and for paris after world update 4, next up is the Nordics … Asobo please dont mess up my hometown Copenhagen!
