Still images in Fortnite (Fps Drops)?

Have been a few days, still images in the game. Have everything already tried what I came up with.

Graphics card driver is up to date

Game was reinstalled

PC was newly set up just a few days ago

Here's a video of what it looks like with me

My system looks like this:

Processor: Xeon E3-1231V3 @ 3.40 Ghz

Motherboard: ASRock H87 Pro4

Graphics Card: MSI GeForce RTX2080 Gaming X Trio

Total RAM: 12.0 GB (DDR3)

be quiet! BQT E9 Straight Power PC Power Supply (500 Watt)

Housing: be quiet silent base 800

Someone ne idea what that might be or what I can do about it: /?

By MSI Afterburner I have been able to determine these values after about 1.5 hours playing

For a few days it is synonymous with me and fortnite has also said that many have so it is not s.der pc
