Sturggling to keep up FPS

[mangus]

I was looking at my ingame settings and noticed that the game is struggling to keep up fps on my pc. I believe i have rather tdecent hardware so not sure what can be causing this

These are my settings at the moment (taken from inside castrum fulminis duty unsynced alone before starting)

My pc is running:
AMD Ryzen 9 5950X 16-core 3.40GHz (barely reaching 20%)
128GB RAM (barely reeaching 16%)
NVIDIA GeForce RTX3090

2 monitors, each LG Ultra HD 3840x 2160 60Hz

seems roughly same result if i go full screen or borderless windowed

Connection speed is around 1Gbps
