Fortnite microfreezes

these microfreezes began after updating the video driver, already rolled back and reinstalled, it does not help, maybe you need to roll back to a certain version?

I have a stable 150+ fps, (approximately) every 15 seconds drops to 40-50 fps, it is very annoying, I have already tried the most minimal settings with 800x600 and nothing, exactly the same drops. I don't know what to do, there is no overheating, the turbo boost was removed, I changed the power modes .. nothing, I also changed the location of the game from hard drive to ssd and nothing .. ((
