Fortnite seidt performance mode no longer loads the map correctly?

I have the performance mode in Fortnite and since 3 days the map no longer loads correctly (I have the performance mode since the beginning)
so the trees, stairs, etc. Do not load everything so everything bugs around eg the trees are just green, what can I do about it?

Turn off performance mode.

Then I have laggs

When I turned it on, I had it right away

Not me

Load a previous save where it was not activated. Otherwise it has nothing to do with the savegame.

How do you mean?

This is the graphic from the performance mode.

But before where I was wearing it, it wasn't like that

I don't know, maybe change the rendering mode

What is there. The mode has probably influenced your savegame, so you should load an earlier game where it was not yet active.

If that doesn't work in Fortnite, I'm sorry, don't play the game.

So do you mean that I should just turn the performance mode out?

What is render mode?

One of them is called DirectX12 and two others, I think, just look for it in the settings, it can be called differently

If I change that then I'll have laggs again

No idea

They got an update.

So for me it is mostly the same at the beginning

It says what I mean up there! I can't explain this otherwise. Mode off and load an older savegame, if Fortnite doesn't have this then my solution doesn't work.
