Bug ID: 58575
           Summary: Low performance in an old Directx8 Sonic fangame in
                    wined3d
           Product: Wine
           Version: 10.11
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: d3d

This game has a built-in fps counter. After launching it, I was surprised to
find that it ran at only 30 fps in the hub area, while on windows it runs at
60. It is seemingly ok in the gameplay, but fps is often several values short
of 60, and there are also rarer drops to 30 for several seconds. There are no
warnings in the console other than related to directsound. DXVK works at a
locked 60 fps, so that means that it's a problem with wined3d.
