Summary: Thief D3D renders VERY slowly, with blocks of colour
                    drawn
           Product: Wine
           Version: 0.9.18.
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: wine-directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

As of version 0.9.16:
 In Thief: The Dark Project (Gold) Direct3D renders very slowly - roughly one
frame a minute - and is sporadically overdrawn with solid blocks of Red, Yellow,
Cyan, Magenta
Runs very well under 0.9.15.
Gfx card is Nvidia TNT2 with 16MB vram.
As of 0.9.16 noticed new TRACE output from dlls/wined3d/device.c 
"..IWineD3DDeviceImpl_GetAvailableTextureMem: stub, emulating 64MB for now"
This code hasn't changed since 0.9.15, it's just started being called!
Might not be helpful, but recompiling with "static unsigned int
emulated_textureram = 16*1024*1024" - to match my GFX card's actual VideoRam
doesn't fix.

To reproduce - simply start/load game - menu system runs as normal, loads game,
then game engine runs as described.

On x86, Gentoo Linux, Xorg-7.0
