My X-Plane 10 had a 4.5TB installation just for the tiles. You was able to use google tiles as scenery back in the FSX days. You can store FS map data and this is nothing new. My pathetic internet as not up to that sadly Originally posted by Mark:MS did pretty well with FS but remember that the map data is not locally stored, you need a good fast internet connection because the data is fetched as needed.
