First time I ran it - everything was fine. Closed and restarted game (Mirrors Edge) and all of a sudden everything is being rendered too low and being cut off the screen (Upper half of screen is black, empty space, low half is the top half of the game)
Reformatted PC as well - re-installed everything from scratch; same issue.
Windows 8.1
