I've googled that z-Buffer of yours and quite frankly, I'm not sure if not having it is a good thing or not. I'd be saying that it's not good although z-buffering seems very demanding and buggy but what about optimization?
Unless what you meant is that the z-buffering will be handled by the GPU leaving a big chunk of the ram free to do other graphics operation but if that would be the case, that would mean that the GPU unit has it's own ram for the matter doesn't it?
Which therefore pretty much answers my question, my understanding: z-Buffering won't be possible :wacko:
