I have low FPS despite good hardware?

I have little FPS despite good hardware. I saw on Youtube that the same hardware generates 150-200 FPS with Fortnite, but I get 70-110 FPS
My hardware:
RT 5700 XT Red Devil
Ryzen 5 3600X
16Gb Ram
I have the game on esports mode and even the settings on low.

Are all drivers correctly installed? Graphics card driver and the mainboard chipset driver? If not you should install it. It is best to always have the latest version.

I just downloaded the drivers from the graphics card externally. Otherwise I check regularly with Driver Booster whether the drivers are up to date. I sit down today and download the drivers from the motherboard manufacturer's site and check whether the driver for the graphics card is up to date. Thanks for the hint. I then report mixedh with the result.
