The city is not loading, please help. (LA Noire)

The city does not load when I go to a crime scene and other places, And sometimes in videos, the sound disappears for a short time, and then appears. Help solve the problem, please, especially with the loading of the city. Basically, the city is loaded, but when I drive through the streets, some as if they do not have time to load, and I have to stand and wait about 1-2 minutes for the place to be loaded.
