I recently bought and installed an Amd Sapphire 5700XT Nitro +. The problem is that at least on low settings in Fortnite should have 300-400 Fps but I only have 150-200Fps. With my previous much worse 2060 MINI with a cooler I had 200-300Fps.

All my components in the PC
Processor: Ryzen 5 2600x
Mainboard: A320 M-A Pro
Power supply: 600 watts
Graphics card: Sapphire 5700XT Nitro +

What should I do with it?
