Fortnite FPS problems with RTX 2060?

About 2 months ago I bought my PC with an rtx 2060 6GB.

In every game where I play I have 140-200fps despite mediocre settings and in fortnite with completely low 70-120fps that feel mega laggy.

I wanted to ask if others also have the problem and how I can fix it.

My graphics driver is up to date.

I wanted to ask if it could be on the monitor because I play at 60hz.

70-130fps = laggy although you have me 60hz?

It just feels laggy and the game is mega delayed

How is your line Which ping? WLAN or lan?

Believe very much that it's Fortnie. I mean it's the only game that does that and you're not the only one with the "problem"

WLAN with 20 ping without packets

What kind of line do you have?

I don't know exactly. Usually 10-17mbit for downloads

It's probably up to Fortnite. Everyone says the game is e-sports optimized. But it is not. Play the game with your "laggy" 70-120 (laggy?) Fps or leave it.
