My rx580 a few days ago I always went to 300 fps in fortnite for example, I was optimizing Windows, restart the pc and suddenly it did not go above 100fps. My pc only works with graphics since my processor is the Ryzen 5 1600 af, which does not have integrated graphics. Temperatures when playing used to be normal. Restart Windows from scratch to see if you configure something but no, it was still the same, I downloaded the newest drivers that can and nothing. I need help.
