Hi Gend0, this is probably an issue for wine devs mailing list. If you ask politely, you may get some comments from the d3d devs. There's also a wiki page, http://wiki.winehq.org/WineD3DOnWindows, where you may describe your experience. Note that the official WineD3D on Windows project is more or less dormant at the moment. The latest official packages are from 2010. VirtualBox is supposed to use Wine's DirectX, though they are probably compiling their own version. So you probably shouldn't expect too much at the moment, afair there were plans to release a wined3d version that e.g. would bring DX10 to WinXP, once DX10 is somewhat working in wine. But that may still take some time.
