[BUG] FPS dies for no reason

Hello! Stumbled into random HUGE FPS drops when aiming with any magnification scopes on Woods for no reason. When I look in direction of sunken village, or sawmill from the sunken village, my fps drops from stable 70 down to 7-14, and frametime jumps from 60-70ms to 300+.
In the same vein i have HUGE lag when Tagilla is on factory, with the same drops. I'm not sure what causes this, can someone help?

Laptop is Aorus 15 XE4 (RTX3070Ti Laptop, Core I7-12700H and 32GB of DDR4 memory running at 3666MHz. Game is installed on M.2 SSD and it has 120+ GB free space)
