Shadows do not render correctly in "The Secret World," an MMORPG that is getting a relaunch later this year, using Staging (CSMT) or not.
Staging has more changes than just CSMT. It's not clear to me if you did already try with plain Wine, can you confirm that it's broken for you in the same way there?
Also, what Wine version did you test with?
