Hello everyone some of you are familiar with openGL nd directX ? i was trying to launch an old game through wine and it returned a strange openGL error : err:d3d7:IDirect3DImpl_7_CreateDevice The application wants to create a Direct3D device, but non-opengl surfaces are set in the registry. Please set the surface implementation to opengl or autodetection to allow 3D rendering err:d3d:wined3d_unregister_window Window 0x30076 is not registered with wined3d. someone knows what " non-opengl surfaces are set in the registry" means? it sounds like a generic error....
