Fortnite, Warzone?

I have a question, is a copper line enough to play Fortnite. The same applies to warzone.

So without wool you can bend everything…

Sure long, the question is how do you define "copper wire"? Coax is just like 2-wire copper. As long as the ping is correct, the rest is almost irrelevant. The only thing where the speed will be noticeable is the download of the game or the updates. With a small connection that can logically take a while.
