stuttering and FPS drops

I recently bought bf6, and I've discovered an extremely annoying problem.

It's like this: when I play casual games with bots, my FPS drops to 50 at random moments, and the game seems to slow down. However, after a while, everything stabilizes. I've tried everything, including reinstalling drivers, cleaning my PC, reinstalling the game, and more.
