I will be in a huge mob and have FPS consistently over 80 fps in 1440p. I have all my setting set to low to try to help and vsync on. It doesn’t really matter in game is in what level from low to ultra. When the mobs get get large, the game gets real laggy and my fps drop between 10-20. I usually end up dying.
i5-8600k OC to 5.1

I have zero issues on any other games I play such as dota 2, cod AW/warzone, madden 20, or grim dawn.
