I got an MSI Ventus 2080 Super for Christmas I have experienced fps problems in Fortnite ever since. However, it works randomly sometimes. When I get lucky I get 200-350fps but every other time I get lower than 80 no matter where at 1440p. When I change graphics from low to epic with raytracing my fps stays the same. My thermals are fine, neither CPU nor GPU is at 100% usage, and only happens in Fortnite and no other game. I would love some help and get this working properly, thanks.
