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@winehq.org ReportedBy: roy@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.
