"Allegro will handle any necessary vertical retrace synchronisation when
page flipping, so you don't need to call vsync() before it. This means
that show_video_bitmap() has the same time delay effects as vsync()."

This is true for GFX_DIRECTX_FULLSCREEN, but not for GFX_DIRECTX_WINDOWED,
though vsync is supported when windowed.
