That world is drawn from Bing map data, of which it has access to two petabytes (two million gigabytes) of, streaming via an internet connection. So even that 150GB isn’t all the data that Microsoft Flight Simulator uses to create its world, weather, and flight mechanics. In addition to hard drive space the system requirements also request a minimum of 5 mbps of bandwidth (50 mbps ideally), indicating that data streaming is a vital part of the game.
As for your GPU, Microsoft asks that you ideally have the expensive Radeon VII or Nvidia RTX 2080 cards, but recommends the older Radeon RX 590 or Nvidia GTX 970. If your machine is feeling its age, though, the minimum specs also support the Radeon RX 570 and Nvidia GTX 770. 8GB of RAM is the minimum requirement, but the ideal spec asks for 32GB.

Recommended processors are the Ryzen 5 1500X and Intel i5-8400, but the more recent Ryzen 7 Pro 2700X and Intel i7-9800X are suggested for ideal specification. Minimum specs call for the Ryzen 3 1200 or Intel i5-4460.
