Fortnite saves the world?

Moin, I just bought Save the World from Fortnite, but it only runs at 30fps even though Battle Royale also runs at 60 dpa…

The LPs always look good on YT, does anyone know if that's because of the game or if I can still help?
(Play on Xbox One X)

On ps4 and Xbox, only 30 fps go in rdw

That's not true.

On Xbox One S and X, you can set the fps to 60fps

You have to "open" the lock of the refresh rate in the settings.

Then you get 60fps

But how does it work?
