W-buffer's been around for yonks, even B3D supports Z/W-buffer and it worked wayyy back when b3d first came out on all the systems I tried it on :)
However, the fact that one is better than the other seemed a bit flawed, some systems worked better with Z buffer, some with W buffer, and some times it didn't matter what colour bit.
But where Z buffer had fighting, I could usually fix it with a W buffer. IIRC.
