I'm splitting this off since it's presumably unrelated to general graphics
slowness in Assassin's Creed.

Other people have played the game without reporting this issue, but for me (and
some others) the characters have messed up vertices - see the image attachment.

Only happens on the characters, not background walls, etc (as far as I can
tell).
I've confirmed it exists in 1.1.5, 1.0 and 0.9.61.  None of the in-game
graphics options seem to affect this problem - any hints on what else I can do
to help narrow this down?
