Incomprehensible lags in games.

In April, I bought components pc, collected a comp and began to tear his ass hiking in the service center, from which he was already very tired.
There are no problems with the PC itself, except that the games are laid.
Lag can absolutely any game, no matter on what settings, it is clearly not in the wrong selection of iron, everything should work well.
1. What lags are taking place? It's a little hard for me to explain, to paint the problems that occur in some games.
A) Dead By Daylight. The whole game goes smoothly at 120 fps on low, 70 on medium and 60 on high. The only problem is the twitching when entering the game. That is, when I choose who to play (survivor or man) I throws in the menu with a skin of a character, which can be twisted with a mouse, as in cs go in the main menu. The character spins not smoothly, jerks, there are tearing stripes on the skin at the time of scrolling. Also, when the game starts, the game has a system of skill checks (it's a circle, with a cursor that spins on it, as well as a small area in which this cursor needs to get in, pressing the key space) So this skill check brakes just like the skin in the main menu, sometimes it seems that it at 10-30 fps works, most often it is noticeable when the screen is a lot of events (music plays , there are many characters next to you, rain, fire, etc.), but the phps remains stable 120. I tried to put all sorts of confits, change the resolution of the screen, remove vertical synchronization, limit the phps to the screen - nothing it did not help. I demolished the wind once a hundred, once after reinstalling the wind came into the dbd and after a couple of alt tab - lags have passed, everything was perfect smoothly, but then everything came back.
B) Valorant, GTA 5, Dayz and many other games. This point is the biggest problem. In all games at 100 fps during heavy frames, when there is a lot of everything on the screen - the games become not smooth. If we talk about phps below hertsovka, in principle it is clear why it happens, but this problem I have occurs in 130 fps.
My build:
ryzen 5 2600x (please without: tafk y tfebya rifvzen fto you hoteffl nyado was dumafing prefje thu buy)
saphire pulse rx 570 8 gb
16GB hyperx on 2666 sort - two by 8
ssd from Samsung
Mother asus b450 mk prime
Monique 75 Hz supporting free sync (already dumping all problems on it)

The inet is stable, the wood is all standing (chipset, graphics card, audio, the freshest bios). In the stress test of the gpu in aida 64 there are friezes in the system, the service says all ok (let die ksta), the gpu I have already changed to exactly the same, the problem remained.


Pysh: So tired of this trawl that I'm going to put 1k on the map who's going to help solve this issue.
