After upgrading my gpu from nvidia 1650 to intel arc b580, I've been experiencing an issue with fortnite. Before it would get around 120 fps but now whatever the settings are it just stays at 5-12 fps and I don't know where this issue comes from. Every other game I've played I have no issues but with fortnite It's just unplayable. I tried uninstalling it but It didn't work I would love if someone could help me.
