Welcome to photogrammetry. That’s just how it is. You can pick between a melted and smudgy version of real life, or a clean and crisp generic world that isn’t real. I like to do the former, and then just not get that close to it.
Some people have issues with it because it doesn’t look great close up or that it doesn’t load correctly. Personally I have no problem - it’s a flight sim, and photogrammetry is designed to be seen from above and from at least a reasonable distance. Try comparing NY with it on and off and you’ll see the difference it makes. Anyway, you can just turn it off if you don’t like it.
Photogrammetry looks great at the right distance. Too far and it’s all crude and pointy, too close and it’s a mess. Not all PG areas are the same, far from it. London has the highest resolution detail, but also the most noise. Amsterdam and Paris, most recent additions, are higher detail than the original ones, but less than London. The original data only has about one third the data density of London, but is much better optimized with far less noise.
PG looks great in small planes. Jets go too fast and too high to enjoy it. Helicopters go too low, too close to the scenery.
I turned it off in the end because although it’s less realistic, cities when seen from a plane look very nice and crisp, and you get this effect without PG.
With PG on it’s somewhat more of a fluid, blurry, image, not what I expect to see from above.
