Unless you're in full screen mode, you're restricted to the actual
target visual which on a modern machine is going to be 32 bit. 16 bit
colour needs to undergo a transform to 24/32 bit.
Assuming you're just blitting straight to the video framebuffer, you'll
most likely get better results in a 32 bit visual.
Anyway, if you're going to the trouble to write this code, why would
you use direct3D? You could just as easily use SDL, or even OpenGL, and
have code that'll run on practically anything.
