game stuttering makes game unplayable

rig:
AMD Ryzen 9 5900x
32gb ddr4 3600Mhz
1Tb m.2 nvme ssd ( installed on windows drive)
RTX 3070TI

The game runs like crap! constant stuttering and stalling. sometimes you can be running along and nothing on screen then suddenly Bang! I am dead and the screen is filled with monsters with no warning and the shader graph is always at max too

I have tried several settings even capping my rig to 60fps and different DX and Vulkan but nothing helps.

Please sort this out as paying for a game that does not work is a bit much.
