24-bit with ddraw

If windows won't let you switch into 24 bpp its likely your card dosen't support it.

I heard that although some cards support both, it's only because the driver really supports one, and just maps the other to it (i.e., the card supports 24-bit, but can also use 32-bit by ignoring the alpha information). Some cards use the alpha information (the upper 8 bits of the 32) and that's why they don't function with 24-bit modes. Perhaps it has a lot to do with the particular chipset the board uses and performance reasons. I think that several companies haved either added or dropped support for certain color depths from one driver release to the next because of performance gain/loss.
Anyway, I am not trying to sound like an authority on the situation; just raising some interesting questions in the hopes that someone will answer them.
