Glide 3.0 (latest official 3Dfx drivers) + V5 5500 = 16 bit z and w (only)
Glide 3.0 (5 different unofficial drivers) + V5 5500 = 16 bit z and w (only)
This means 24-bit depth was not available with Glide API at all.

Perhaps some of you are wondering what the heck is this?
Well, yes, I was wrong. It's not widely used (only in some 3dfxvgl titles and only with VSA-100 hardware), but 24-bit Z in Glide 3.0 does exist, even though the capability is not exposed by the drivers. Perhaps backward compatibility was the reason why 3dfx hid it.
