           Summary: Heroes of Might & Magic 4 - battle scene is slow unless
                    mouse is moving constantly
           Product: Wine
           Version: 0.9.5.
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-directx
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: martyspamtrap(a)comcast.net


In a battle scene in HOMM4, animation is very slow, and CPU use is very *low*
unless the user moves the mouse around in continuous motion.  While the user is
moving the mouse, animation occurs at full normal speed and CPU use is normal.

I suspect that since the mouse is a software drawn mouse cursor, it forces a
screen update when the mouse is moved.  The normal code responsible for
maintaining the frame rate seems to be in error, throttling the frame rate back
way further than necessary, and moving the mouse overrides this because it
forces the update.

The same effect is noticed when on the video when the battle is over, where the
battle's stats are shown.

Please let me know if I can do anything to provide more useful information on
the subject.
