I play on the lowest settings on fortnite with a lower resolution and about 70% render scaling and yet I still only get average 60fps in the lobby. When I enter the battle bus it goes over 100 and when I am fighting it averages 100, My GPU is GTX 1050 Ti and CPU is i7 3770k, I have tried a virus scan on Malware bytes and it just came up with PUP's, I tried the game again and it was still the same, I just got the card today so the drivers are up to date.
