[Wine] Re: winetricks Directx9: Unsupported style(s) 0x144

The only part we really use from native directx9 are d3dx9_* helper dlls. The core of DirectX9 namely d3d9.dll is provided by Wine and it makes Direct3D9 to OpenGL. If performance is low it is likely because you are using slow video drivers or a slow videocard OR your 32-bit opengl drivers have not been installed correctly.
