It seems to work fine as it is, apart from the fullscreen issue. Performance is the same and I got actually even better loading times than on bootcamp. Running on 10.8.4.
Fun mission, my favourite out of those three. The AI was a bit oversensitive and some parts frustrating, but still, this played and felt like the real thief. Almost makes me want to try the editor. Almost.
If this feature manages to get rid of the sharp pitch black shadows, it's a must have. They're basicly the only thing I dislike about DM's visuals and tend to ruin the atmosphere for me.
Ah, it wasn't all that bad, I didn't encounter that many bugs and the game was reasonably fun - well, as fun as a WW2 shooter can be these days. I give a 7/10.
