Allegro sits on top of DirectX and uses it to draw things, play sounds,
etc.

AFAIK no.

If you are aiming for Quake like action games, no. If you aim for strategy
games or where the screen doesn't need fast updates, stick with Allegro
for portability issues.

AFAIK the problem is you can't use Allegro 2d routines and Direct3D at the
same time sharing the same drawing surface without huge speed penalties,
which renders the use of 3d acceleration useless.

Recently George writting some OpenGL wrapper or so, and someone else wrote
also a 3d interface or something like that... huh, I am not the best
person to answer, since I tend to run away from 3d... You can check the
Allegro homepage for the Addons and Utils pages. Maybe there you can find
something about 3d acceleration.
