Thats why there is a cache, so you don't re download every time.. So only new locations you visit will be streamed, but it will still be way less than having to pre install maps with locations you might never even visit in game... I don't get why this is so hard to grasp.
Do you manually download all your maps from google maps/earth every time before you use it? No you don't, you let the program figure out which parts you actually need and stream it to you. Same exact thing, fot the exact same reason.
Storage is cheap
So is bandwidth. 8gb/h is only 2mb/s which was maybe a lot 25 years ago. These days you can't even get a connection slower than 50/100mb/s
But i was under the impression that games try to be as efficient as possible when it comes to networking.
Games try to be as efficient possible with their network code for real-time updates, so latency is minimalized. This is not at all important if you prefetch stuff minutes before you actually need it.
Do you want wait hours/days before you can actually play? Or only stream what you actually need when you play while you play?
You do that by, hear me out, playing! And the game figures out where exactly you want to play and what you need. Besides, it probably will be an option to preload anyway but I don't know enough about MSFS. And in the case of preloading, you would hit the exact same data cap.
Yes and you only don't fly everywhere in game that you would have to download in these preloaded chunks/regions you're so happy with. If you just intend to stay in the same location, the streaming will stop! Because, everything will be cached....
So you cancel your ISP subscription ever time you finished downloading a game, movie, whatever? No you keep paying so you might as well use it. And if you a data cap, I'm sorry for you. That's a real bummer. But, I don't know why i have to keep repeating this point, the amount of data is at worst the same! (if you have enough storage to keep it all in cache) If you don't want to use more data don't fly to regions you haven't downloaded yet... But this is the exact same as with preloading..
