The chief technical officer at Metro: Last Light developer 4A has described the Wii U's CPU as "horrible" and "slow" when asked whether the title would be ported to Nintendo's new console.
During an interview with Now Gamer, Oles Shishkovtsov claimed there would be difficulties with a Wii U port due to the console's "horrible, slow CPU".
The processing speed of the Wii U's processor is not known, so it is not possible to verify the claim. Other studios, such as Ubisoft Montpellier (Assassin's Creed 3) and Treyarch (Black Ops 2), appear to have successfully ported their high definition games to Nintendo's new system.
Metro publisher THQ, which has been engulfed by two years of consistent finance problems, wants 4A to finish work on Metro Last Light before April (due to assurances made to investors), meaning that there could be a number of reasons why the studio is not focusing its resources on a Wii U port.
Meanwhile, a spokesperson from THQ, Huw Beynon, elaborated on Shishkovtsov's claims.
"We had an early look at it, [and] we thought we could probably do it," he said.
"But in terms of the impact we would make on the overall quality of the game - potentially to its detriment - we just figured it wasn't worth pursuing at this time. It's something we might return to. I really couldn't make any promises, though."
