The game freezes when the camera turns. (The Elder Scrolls 5: Skyrim)

Skyrim freezes when the camera is turned, or rather, it seems to be jerky, that is, when I turn the camera everything seems to want to go back, but it goes forward and all game items and NPCs seem to twitch in jerks. It is also clearly noticeable when I switch to the 3-person camera, when I switch it, the camera goes back from me and it goes in jerks. When I tried to start the game in windowed mode, everything became normal and these friezes disappeared or became completely invisible, in general, in windowed mode it is much better.
Mods are not worth it, the game is licensed with all additions, I include free mega textures.
Comp: 8GB of RAM, AMD Radeon 6950 (2GB), i7 2600k
These friezes appeared after a long time without prejudice to it, and once entering the game I noticed these friezes, while nothing changed on the computer and any programs were not installed either. Startup and so on are also clean when playing, no third-party processes are running.
