Hi, I''m really new to programming in c/c++ and I have this question from a friend of mine that I can''t answer(because I don''t really know any DX programming). He kind of thinks I''m a programming God, but I really only do VB, and am still learning C/C++. I am wondering, is it an emulated layer in D3D?, or are calls to DD just forwarded to d3d????? Here''s the hypothetical question he''s posing:

Say for instance, I have an app that is streaming video, from say the USB interface or a capture card. I have the video stream previewing in an overlay on a directdraw window and this was created in DX6.x or 7.0. I then have the ability to record the stream while it''s being previewed. With DD in DX7.0 & below this isn''t a problem even on some slower systems(read ~300mhz), but from some of the ''rumors'' I''ve heard about DX8 & DD this might cause some unneeded overhead in my app. Am I unnecessarily worried, or do I need to rewrite and recompile my app to optimize it for DX8 before customers start complaining about choppy video or other problems?

Well, since no one else wants to say anything, I''ll throw in my meagre 2c.

Dx8 SDK ships with DirectDraw7 ... there is no DirectDraw8
