Soundwave, I tried looking all I found was a referance to something on neogaf, with a guy saying he found some patent.

"In graphics processing data is received representing one or more vertices for a scene in a virtual space. Primitive assembly is performed on the vertices to compute projections of the vertices from virtual space onto a viewport of the scene in a screen space of a display device containing a plurality of pixels, the plurality of pixels being subdivided into a plurality of subsections. Scan conversion determines which pixels of the plurality of pixels are part of each primitive that has been converted to screen space coordinates. Coarse rasterization for each primitive determines which subsection or subsections the primitive overlaps. Metadata associated with the subsection a primitive overlaps determines a pixel resolution for the subsection. The metadata is used in processing pixels for the subsection to generate final pixel values for the viewport of the scene that is displayed on the display device in such a way that parts of the scene in two different subsections have different pixel resolution."
Varying effective resolution by altering rasterization parameters.
This sounds like a cost saveings technique.
Ei. instead of checkerboarding.
*edit:
Apparently this cerny patent, links back to another they have on VRR (variable rasterization rate).
