--- Comment #37 from spammaster@madtracker.net 2010-03-04 15:21:58 --- Too late to confirm (bug has allready been marked as fixed) but to my great joy updating to the new 195.36.08 driver has solved the problem for me as well :)
This on a geforce GTS-250. Looks like all geforce users can now enjoy morrowind on wine the way it was meant to be played.
