Attempted to post about this before- but for some reason did not show.

When I start the game, I get a severe graphical glitch where character faces (main character, his sister's face, etc.) do not show, and many textures become invisible.

Google searches didn't reveal anything on how to fix this- although it did reveal a similar bug for Assassin's Creed in the past- called the horror bug or something (floating eyeballs, etc- very similar to what I was seeing)

Would appreciate feedback on how I might go about trying to solve this.
