Fortnite lay Pc Amd Radeon 5700 xt?

I've had problems with Fortnite for a month (see video). The graphics card goes crazy when I open Fortnite. Graphics card new, benchmark everything works fine. Does anyone know what's going on? Thanks in advance! Ä.

What media is the game installed on? SSD is recommended. In addition, reinstall Radeon drivers (before possibly throwing down with DDU)

NVMe SSD. I'm trying again with the latest driver.
