[Feature Request] Add P2P (torrent) download option

[QPUNeptune]

I dont know how complicated it is to do this, but imma give it a shot anyway. I have no idea if i was tried or if someone requested it. I had this thought when i remembered that the War Thunder had this.

The way this works is pretty much as a torrent client (what a shocker), but just for delivering the games' files. Note that this option is TO HELP the download that is already doing, not to replace it. An example: assuming the normal download speed is 5MiB/s, enabling the P2P, which adds 2.5MiB/s in this case, would have the download speed theoretically reach 7.5MiB/s (again, this is an example).

By adding this option, i reckon that it could improve the download speed of the games. Of course it also needs a way to disable it, some people doesnt want it.

Anyway its more like a suggestion, and sorry for the bad english.

直接多线程下就已经挺快了？起码能跑到70多M，感觉也够用了吧

Heyo, thanks for your suggestion! While we think it's a great idea, there are a number of risks involved with the proposal, notably:

• We would have no control over the files shared in P2P. This means that a malicious actor could potentially modify game files and put people's systems at risk.
• The game data files are subject to miHoYo/Cognosphere Ltd's copyright, and as such, we believe that there is an increased risk of getting a C&D from them due to the "illegal" distribution of official game data. Furthermore, as per our Contributing Guidelines, we are not planning on implementing features which violate the Terms of Service of any game currently in live operation by miHoYo/Cognosphere Ltd. We encourage you to read the Terms of Service of each title to get a better understanding of the rules by which we are bound.
• Even if we would have implemented this feature, the current tested maximum game data download speed that we know of as developers is around the 100MB/s mark. This means that, while a P2P solution could, in theory accelerate download speed, in practice, it would depend on the number of peers (hosts/machines) that actively seed the game data package. There is also the added argument that, knowing that we can download the game's data at a rate of 100MB/s, there is little advantage in trying to squeeze out an extra 2.5MiB/s, especially because of the points listed above.

War Thunder's situation uses a different method of downloading their game data package. We opted with the safer, direct download approach. That's not to say that P2P is a bad way of doing it; it's just not ideal in our case because of the risks involved with integrating such a solution. Hopefully that clears things up!

Ah no problem, thank for clarifying!
