--- Comment #3 from H. Verbeet hverbeet@gmail.com 2008-10-28 17:59:15 --- Wine implements most of Direct3D 9, but d3dx9_27.dll is an utility dll on top of d3d9 that's mostly unimplemented in Wine at the moment. Typically applications should install this dll as part of their installation, but some applications don't, and sometimes the installer doesn't work. IIRC newer versions of the DirectX runtime installer need some things from fusion.dll that we don't implement yet.
