More FPS in Fortnite Endgame?

Please only answer my question if you are familiar with computer hardware / games (Fortnite)!

Hi,

I've had a new PC for a week. In Fortnite, I always manage 144 FPS… Only in the endgame (play professionally Fortnite) my FPS constantly drop down to 80-90 and it just doesn't work anymore! My ingame settings are all low! Are there any Windows settings or anything else so I can get more FPS? My PC is actually relatively good…

PC:

GeForce RTX 2070 Super

Intel (R) Core (TM) i7-7800X CPU @ 3.50GHz

15.73 GB RAM

1920x1080, 16: 9

Did you overclock anything?

Apart from the fact that your CPU is not a good choice for a gaming PC, everyone gets massive frame drops in real endgames (50/50 zone with 25+ opponents).

Unfortunately, you can't change that.

Well I've already tried a few things like: Energy setting: maximum performance clicked on the PC…

but before that I had little FPS in the endgame and when I stopped it the FPS got better. Still not good

Ok, thanks for your answer
