Fortnite bug image blurry?

I have a bug in Fortnite on the pc. The picture always looks blurry. I tried to adjust the resolution, tried all possible graphics settings, but nothing helps. I have the problem, by the way, in the lobby and in the game.

Do you have G Sync or something similar?

Resolution?

So it would be interesting what kind of PC you have, what kind of monitor, generally whether you have a newer setup or an older one etc

Who still plays the Fortnite xD?
