Recently I dusted off the old Thief 2 game and decided to play it again. For some reason, however, I cannot seem to sneak. As I remember, the sneak key is the left CTRL key. But the character does not crouch and movement speed does not slow down at all. Seems to me that it did in the old days. Also, they seem to see me even when I'm in shadow while sneaking. Is there something I am missing?
