             Bug #: 29105
           Summary: Stutter during file loading using DirectX
           Product: Wine
           Version: 1.3.32
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: roy at marples.name
    Classification: Unclassified


When things load using the DirectX renderer, the on screen display stutters. As
in there is a noticeable stop and then continues.

This is heavily evident in Starcraft and World of Warcraft.

I think this is a bug with the DirectX component as when using the OpenGL
renderer for warcraft (ie, effectively bypassing DirectX emulation) there is no
stutter. The same amount of disk activity occurs though, which suggests that
something in the DirectX emulation is blocking the thread.

If this could be fixed then it will probably improve the performance of many
games.

There's probably a duplicate bug about this, but I couldn't find anything and I
cannot really provide anything more technical.
