Call of Duty: Black Ops 2 has come under fire, but for different reasons this week with the Wii U version in question.
Whilst the studio behind the Wii U edition, Treyarch, have had considerably less time to develop and refine the Nintendo port, eagle-eyed players have noticed performance dips.
In a Eurogamer feature, the Wii U edition came out with a handful of positives, with the visual quality come up on par with the Xbox 360 edition - "aside from gamma issues, we're essentially looking at exactly the same presentation".
The Wii U edition of Black Ops 2 also boasts 2x multi-sampling anti-aliasing (MSAA) at a hardware level.
Despite having a solid visual quality, the Wii U edition struggles when it comes to performance, with framerate issues throughout more complex scenes. In one scenario the Xbox 360 maintained a rate of around 50fps, the PS3fps at 46 and the Wii U version dropping as low as 26fps.
Mirroring the game on the GamePad has had frame-rate drops as expected, however the resolution and visual quality itself is maintained.
The Wii U version is the least optimised given the studio's short time working with the new hardware, there is potential given the graphical detail that can be achieved. However with inconsistent performance issues may leave players frustrated during crucial moments.
