GPU Low Usage And CPU Goes To <80%?

[Shadozz]

So I've had my pc for almost a year (to play mainly fortnite and other games) but in the last 6 months i have had a problem with my fps. From 144+ with ease to 120 FPS max. My main concern is my graphics card because one of my friends who kinda knows about pc wasnt sure about my GPU and asked me to tell him how will the card perform. I've tried anything to fix the issue but it nothing worked.
Specs:
2x8 gb ram 3200MHz

MSI Radeon RX 5700 XT 8GB Gaming X :https://www.msi.com/Graphics-Card/Radeon-RX-5700-XT-GAMING-X

AMD Ryzen 5 2600X

SSD: Kingston 480GB A400
