Summary: Command and Conquer Generals (Zero Hour) slows down
                    massively when smooth water edges are enabled
           Product: Wine
           Version: CVS
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

As per the title, this slows the game down from 50-60fps to 10-15fps (where as
my machine runs it with all options fine in Windows). This may be a bug or
purely an optimisational issue but it shouldn't create such a massive
performance hit. This sounds incredibly vague so I'll provide any detail you
request.
