Hi all. Thanks for posting this. Im the creator of the video in the first post, and I personally find this FS2020 mod to be truly amazing (big thanks to the mod creator of copurse, as Im not taking any credits here).
Especially if you are flying in remote areas, small cities or just in the middle of nowhere, the Google textures are just so much better (in most cases). The textures are way better updated, specifically in Europe and there are areas around the world that Bing doesnt even cover - which Google does, in China, Russia etc.
Regarding performance, I havent seen any difference in terms of frame rate really, although I do believe more VRAM might be used since the textures are mostly more detailed and therefore probably also larger in size.
As seen in the video, here are two examples on how much better it looks in my hometown, Sweden (near Arlanda airport):
