CobraEye, no one believes you by now, why don't you just quit? From your statement it becomes very clear you have no valid experience with Vue and you have no idea what you're talking about. If you want to talk about something, do yourself a favour and learn about it first or you just sound ridiculous.

DOF in Vue 7 is not grainy and, although is not as fast as adding it in post (obviously!) is not impossibly slow, especially the hybrid 2.5D. My image was rendered in about 8 hours but it also has Global Radiosity, soft shadows and lots and lots of polygons.

Regarding adding DOF in postwork, the results are not as good, IMO, because of the deficient AA in the z-depth image that Vue produces. This is not noticeable for large objects (buildings, etc) but it becomes noticeable with small blades of grass or tree leaves, for example.

So, CobraEye, if you want to talk bad about something, which seems to be the only thing that you're capable of, talk about z-depth image. Vue's z-depth image is still not as good as Bryce's, for example.
