So let's recap. What we know of the Wii U spec strongly suggests that the new Nintendo machine should be something along the lines of an enhanced Xbox 360. We have a tri-core IBM CPU, an improved, more modern AMD Radeon graphics core, twice as much RAM available to developers and we even see a substantial boost in the volume of fast eDRAM directly attached to the GPU. There are trade-offs in any console design, but the key ingredients suggest that 360 ports should transition across to the new hardware fairly easily. Unfortunately, Call of Duty: Black Ops 2 proves that the situation is not quite so straightforward.
Based on a visual analysis at least, it seems clear that developer Treyarch thought its best bet in bringing Black Ops 2 to the Wii U was to transplant its existing Xbox 360 work lock, stock and barrel across to the new hardware. In putting together our usual comparison videos and galleries, what struck us was the level of parity between the 360 and Wii U games - aside from gamma issues, we're essentially looking at exactly the same presentation.
All of this means that the new version gets the same 880x720 native resolution, with the same sharp upscaling filter employed on the Xbox 360 release. There's even 2x multi-sampling anti-aliasing (MSAA) - the first time we've seen hardware AA deployed in-game on a Wii U title (admittedly, it's early days there).
