--- Comment #1 from Rico kgbricola@web.de 2013-06-22 05:00:06 CDT --- Why do you think this is a d3dx bug? Does it help if you use one of the native d3dx9_xx.dll ? Which exact version is the game using? Are you really sure this is a d3dx9 bug? (see http://bugs.winehq.org/describecomponents.cgi?product=Wine for details)
