Sounds like only you are having this problem no one else has reported this issue , you can check your drivers if they are uptodate thanks.
Have you considered adding multiplayer...where 1 player can be the yandere and one up to 3 can be a normal player...with the same options of hiding and all that ...i think it would be fun playing a multiplayer horror game with friends...or even a co-op mode where 1-3 players play against the AI yandere...also one person can fit in a locker at a time
