Assuming you mean 2020, it's impressive for a game but not Google earth. Flying through a desert (even a desert city with photogrammetry!) and the interpolated trees that get added in would make you think you're flying over a lush forest in the pacific northwest. It also struggles a lot with non-solid 3d objects like bridges, freeway overpasses, etc.

Google earth VR fidelity is terrible anywhere that isn't a big 3D hand mapped city, just like Flight Sim VR. Most places you are just looking at streetview images, without any depth.

Very pretty, but not accurate. Most of the world is not authored, but a best-guess by an AI with procedural models.

(They do have legitimate 3D-scanned areas, and even hand-authored content for specific landmarks and well-known cities, though)

It is not far off from Google Earth. Most of the cities have handscaped 3D models, while the rest of the planet is procedurally generated.

They are continually improving coverage, a 3D artist friend of mine worked with an agency that was providing 3D models for them (wasn't the best workplace though, very factory-floor-panopticon-y).

Though last time I tried it, about a year ago, my hometown (a capital of one of Brazil's states) and all the surrounding areas was still very much procedurally generated. (FLN airport district is next to a mangrove swamp but was represented in-game as grasslands, as well as some very out-of-place building styles)

Do you mean MS Flight sim 2020?

Haven't tried it.
