Invisible sides of box in Direct3D

[Guest_imported]

I create a scene in Direct3D retained mode using delphix. I add multiple boxes (loaded from .x files converted from .3ds files), each to its own frame, to the scene. (At first idirect3drmframe and meshbuilder is created then mesh is loaded to the meshbuilder and this is add by addvisual method to the frame) When I try to move through the scene, some of the sides of boxes aren't visible and everything is extremly slow. Can someone help?

Thanks
Michal

I can't be of much help, but I've tried to use DelphiX in my projects too, and found it to be slow. So I think that DelphiX is causing the slowness of your programs. Try using some other component for your DirectX stuff or use straight Delphi for your component stuff.
