I do not know if it is necessary to write about such errors here.
But I started to have fps in the game after the 40th day. For some reason, fps began to fall in the main room and bedroom from the usual 40 to 11, or even 5 fps.
I thought it was due to rosital's visits to the endless hole, but no, after this event, FPS never returned to normal. I reduced the graphics in the settings, but it did not give any effect, I repeatedly re-entered the game, but it was useless.
I don't know what to do with it, the FPS drops in these two rooms, on the street in the basement and other parts of the map, the FPS is normal.
