Fps <20 in maps + insane shader spikes

As soon as i start mapping, my fps drops dramatically and shader graph spikes like crazy

CPU/GPU/RAM specs
i7-8700K 3.7GHz
rtx 2080
16gb


Graph in the hideout/start of the map (no mobs around)


Graph while mapping


Same results with the lowest/highest graphics settings

UPD: As soon as i join any map, my fps drops to 40-50 fps with max CPU/shader graph. After spawning 10+ monsters, my fps drops to 10.
After entering Alva's incursion my fps goes to 60+ with smooth gameplay until 1- packs of monsters and then my fps drops again.
Tried every setting, etc. Same resulrs

In your Nvidia app is your PhysX processor set to your GPU and not Auto?

The graph is showing your CPU is having frame time issues. These calculations should ideally be placed onto your GPU.

Yes

UPD: moved a shader folder to a ram disk.
Still 20 fps in a crowded map with full shader graph
