DirectX (non-exclusive mode) vs. GDI

Hello!

I need to do fast animation in a MDI child window. While it's clear
that DirectX is much faster than the GDI for full-screen applications,
I've seen comments that there's not much speed up over the GDI if
DirectX is confined to its non-exclusive mode. Can anyone confirm or
dispute this?

thanks!

Depens a bit on what your doing.
3D is for sure faster in DX, but plain 2D is close to as fast as DX as API
Windoze will use the the basic 2D acceleration supported by the board.
