My fps always drop when I am playing this game.
Close every single tab you have, and programs including discord, steam , etc
Disable every single graph in video settings
Disable Xbox game bar
Disable Nvidia overlay if you have GeForce experience
Follow this tenz video for some basic optimization https://youtu.be/i-NucOextD4
If your PC shouldn't be dropping frames but it is, there's a high chance it's temperature related. Maybe it's overheating. Does it happen in other games too?
!specs?
I run val with 100fps avg + discord and spotify sometimes with an athlon 3000g and 8gb
