It sure seems like it. Everything was running fine until I had enabled shadows, and after I did, the game immediately crashed and my computer completely froze up forcing me to restart.
I read some other threads concerning the game/computer freezing and whatnot, and I followed what was prescribed (updated my drivers), but to no avail the game has been, to me at least, rendered unplayable.
It could be a bug or it could be something on my side, I don't know, but I figured I'd at least bring this to someone's attention.
EDIT: Also, each subsequent time I try to play the game, I'm able to log in and choose my character, but after that the game freezes and locks up my computer.
