Hi, if you search for past topics you’ll find that many people have complained about photogrammetry quality since the start of the sim, and especially in London since the UK World Update dropped. The Paris and Amsterdam data sets seem to be particularly “jagged” similar to London.
You’re not doing anything wrong, this is just how it looks. If you’d like to complain about that, I recommend adding new details to one of the existing threads rather than starting a new one.
