Unstable FPS in 1.3.0 (Assassin's Creed: Valhalla)

The problem still appeared in 1.2.1, sometimes the textures were not even loaded and the roofs of houses flew in the air, only the installation of firewood version 466 and on 471 races helped. After 1.3, neither 466 nor 471 help, it is not comfortable to play at all. MB who knows how to fix it?
