Wat houd dit in? Heeft dat veel nut? is dat beter of juist niet?
heb de search gebruikt maar niks speciaal over gevonden..

probeer eens te zoeken met google, ik kreeg net aardig wat results (iets te veel om allemaal door te lezen 
)
hieronder stukje dat ik bij tomshardware vond:

While using the software I had noticed an artifact that led be to believe there was an issue with their z-buffer support. I asked him what it was and he told me that they are using a more efficient z-buffer called a w-buffer that relieves bus bandwidth. It does this by having only to send x/y/w coordinates over the bus while z-buffer in certain circumstances has to send all that plus z. So what's the difference? The w-buffer is more flexible in certain ways but has to be used correctly for visual defects not to appear. One other possible negative side effect of this shortcut is that with games that use the z-buffer to create other special visuals, you might run into visual issues. This isn't a common case in games and isn't really something that game coders commonly do so I wouldn't be too worried about this. In most cases the z-buffer can be used instead of the w-buffer to deal with this. You may lose some performance but you have a working game.
