[Bug 16952] New: Arcanum (and possibly other ddraw 2D games) have very slow rendering

http://bugs.winehq.org/show_bug.cgi?id=16952

Summary: Arcanum (and possibly other ddraw 2D games) have very
                    slow rendering
           Product: Wine
           Version: 1.1.12
          Platform: PC
               URL: http://appdb.winehq.org/objectManager.php?sClass=version
                    &iId=3476
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown

On WINE 1.0.1 Arcanum
(http://appdb.winehq.org/objectManager.php?sClass=version&iId=3476) runs fine,
even on my hardware (laptop with Mobility Radeon 9700, open-source drivers).
However, with the introduction of the new versions (at the moment I can confirm
this happening with 1.1.9 and 1.1.12) Arcanum runs unplayably slow. I have
tried also to run it after installing the proprietary drivers for my graphics
card, but to no avail.

Since exactly the same thing happens with Sid Meier's Civilization III
(http://appdb.winehq.org/objectManager.php?sClass=version&iId=7905), it's
somewhat a reason to believe it happens on many other DirectDraw 2D
applications/games.

Moreover, changing the default ddraw renderer to opengl instead of default in
regedit only makes things worse, regardless of the application.

However, when a 3D application, like World of Warcraft, is introduced, the
rendering is fine, with no noticeable slowdown (actually works a bit better
than in the stable version, at least for me).
