Hey there,
I got a Ryzen 3600, 5700 XT, 32gb Ram, Game installed on an SSD.
Game on Steam.
So far the performance seems somewhat random, one time its fairly stable and decent, other times on the same map with the same modificators, its suddenly horrible. Not just during Hordes or such, just Random Fps Drops in Areas that are totally fine in other runs, be it with a huge amount of enemies, or barely any at all. With or without Fog.
This seems to happen with all kinds of different Graphic settings as well, different stage of FSR 1 / 2, or neither of them, settings from medium to high, Vsync on or off, toggle settings on or off.
Other times the performance seems to get worse the longer i play, where restarting the Game seems to help.
