Fortnite is in full screen mode?

So
- in Hardware
2

Whenever I switch to full-screen mode in Fortnite, it totally lays. When I play in the window mode but everything is normal. Does anyone know if it is due to the hardware or if I have to change something in the setting?

Es

Listing the Hardware to the PC (EVERYTHING!)

Belches operating system? Which build?

Driver in which version (number)?

Monitor (manufacturer, model)?

No info no help.

So

Have already found the answer: had to turn on VSync!

Everyone says that they should let it out, but now it is no longer in full screen mode. Nevertheless, thanks to all who answered
