So I'm now confused, at first it seemed that 24-bit and 16-bit cards may not be worth supporting as a) they may be too slow and b) they may not render Alpha properly. But then we've heard that they may be quite fast on some systems and that alpha should actually work properly (which was my understanding of it and if I make a 16-bit graphics mode in BMax all my particles work fine, unless Bmax is actually still making it 32-bite for some reason...).
