So like, sometimes i can run Fortnite at 1080p epic settings 60 fps. and sometimes when i log into a save the world mission it dips down to like 40 fps with lag spikes every few seconds that go down to like 10 fps. even when i turn it all the way to low settings it doesn't help at all. ive considered resetting my PC but it keeps saying no changes were made.
