--- Comment #3 from Rico kgbricola@web.de 2013-09-14 05:00:20 CDT --- Then it's likely a directx-d3d bug ( see http://bugs.winehq.org/describecomponents.cgi?product=Wine ).
As we don't know if it is an nvidia binary driver bug, could you try the following: - How does it look if you use mesa software rendering? - How does it look with nouveau? - Does the demo have the same issue (if it could get running)?
Did you rate the app "Platinum"? Have you tried wine 1.5.17 as in the test? Every user (also me) who looks in the appdb thinks the game should run without any issues with that version? So should be pretty easy to find the regression, shouldn't it? What did you change between that test and now?
Were there some game updates?
