Does anyone know exactly why using DirectX is faster than the usual
methods of audio output? I have another Windows-based program, Vaz,
which exhibits a similar speedup when using DirectX. I was wondering
if there was something amazing about DirectX, or if it was making
up for a deficiency elsewhere in Windows.
