Which is better..Multi-windowed or Multi-surfaced DirectX app?

I'm starting out a new project that basically will be a DirectX interface with either

1) Tiled windows within the main window, where each window
manages its own primary/background surface and flipping.

OR

2) Using just the entire window and managing multiple surfaces
   (For example: the top-left hand portion of the window is one surface, etc)

Note: I intend to have about 4 to 5 separate sub-windows. One implements
parallax scrolling (borrowing from SAMS book example) and another surface is
essentially a status window. Am I pursuing the correct route, or is it
very easy to set up tiled windows within your app? If option 2 is
more do-able, what's the best strategy on managing the surfaces?

The one I've been thinking about is during each update()
bitblt the surfaces to a background buffer (whole screen)
and then flip it over the primary....

Thanks in advance.

Hi joeycato,

your second choice is faster than the first one. DX windowed applications are slower than exclusive cooperative level. You can bitblt your sprite(s) as different rects in your backbuffer surface attached to the primary and then flip..

hope this helps

I forgot to mention that both options would be windowed-base, so in light of that, would your advice change?

joeycato,

no, I believe your first choice (one main window with tiled windows inside) is slower.
But why do you add other windows to the second solution? You can split your surface using rects...

Thanks
Marco

Thanks, cool, actually that's the way I'm currently designing it (using 1 surface and bitbltting separate rectangles)...I guess I was at a crossroads, because I figured if I were going to have multiple windows, I would want to stay with the Multiple Document Window approach, because it might be a more professional looking interface, but I agree with you, using the rectangle approach does sound better.
