Fortnite uncharged textures and FPS drops?

I started playing Fortnite again since Corona started and tried it on my laptop. However, on the one hand, the textures of the cities no longer load quickly, and on the other hand I often have FPS drops. Fortnite ran perfectly on my laptop 2 years ago and I think my laptop should still be good enough to play Fortnite with low settings. So far I have updated the graphics card driver, checked Fortnite for problems and set all settings to the lowest, nothing really helped. Do you have any ideas why this could be? Thanks in advance 🙏🏼
-Here are the components of my laptop

Is it the internet?

Manual:

1: Delete fortnite

2: hollow warzone or apex

No, I have a 0-7 ping almost all the time

About an anti-virus program?

I always use Ccleaner but I can

Perhaps too many background programs are open, the 8GB RAM is quickly at the limit
