Chaotic FPS drops

My friends and I are faced with the problem of FPS drawdown. The problem occurs regardless of the game mode, map, addons, multiplayer or single player. The main essence of the problem is that once every 5-10 seconds the FPS drops sharply by 60-70 or even more frames and then also sharply restores to the usual values. I can't say exactly how long ago this first appeared, but now I encounter it in every gaming session.

Specifications of my PC:

CPU: I7-13700K
GPU: RTX 4070 Super
RAM: HyperX Fury 32GB
Game installed on SSD
