At the start of the game, FPS drawdown to about 2-5 frames (Fallout 4)

As a matter of fact, I start a new game - the frames drop to zero (pirate, tried the versions of the khatab and mechanics). The version was clean, and then she simply refused to play the video, now I threw one mod from a small collection that I wanted so much to collect - the "light" in front of the character editor was played for about half a minute. It's impossible to edit at all.
According to the performance characteristics of the cogitator:
Processor: AMD Ryzen 5 2600 Six-Core Processor 3.40 GHz
RAM: 8 GB.
Video card: AMD Radeon RX 550 (4GB)
That is, it would seem that the game should work. And she worked a day ago with fairly stable performance, but then something went wrong. Demolished, reinstalled, demolished again. Rebooted. Changed permissions, downloaded files for potato mode. - And nothing has changed.
I put the expander F4SE - there is no difference either. Tried patches - nothing too.
On the screen - the indicators after 15 minutes from switching on, initially the memory is loaded more and the processor too - but the last times, when the game was running, it also loaded, and it seems normal, nothing like that happened.



ps: I may not know anything at all about hardware, etc., but still. Earlier, when I foolishly tried to install Fallout 4 on a laptop that had 4 RAMs with a built-in video card, even the menu did not work there normally, but here the menu flies, and the game itself hangs like a corpse.
