--- Comment #3 from Stefan Dösinger stefan@codeweavers.com --- Yay, don't tell me this game magically needs mismatched depth stencils to work like they do on ATI cards. (Nvidia cards behave like Wine).
Might have some relation to nvapi / RESZ in the sense that the game doesn't resolve the depth buffer but magically gets the right thing by using the "wrong" buffer.
(Note that these are fairly uninformed guesses, I haven't tested the game yet)
