Yeah, I'd been thinking about it, but the problem is how incredibly unclear the 8x4 requirement is. Is it 8x4 alignment of the dispatched primitive, or 8x4 pixels actually lit and sent off to the CC? Once again, we rage at hardware docs describing a derived requirement without describing the cause of that requirement. If I can just leave my surface state the same size and just align my prim's coordinates, that would be awesome, but I expect that's not the case at all. If I have to be able to actually write to all the pixels 8x4 blocks, then I have to go adjust surface states as well.
