My first reply said it was streaming high-res data from the cloud.

Your first reply also stated that it needed 180mbps to stream weather data.

Considering it’s a flight simulator advertising to cover the entire world, most people would intuit that would include textures and 3d models.

You can fit the entire world’s texture and 3d models on a super small file. The file size is entirely dependent on the level of detail of those textures and models. Hence the MS Paint analogy.

I appreciate you not arguing anymore, at least you know when to quit.
