The visually impressive Project CARS is already available on PlayStation 4, Xbox One, and PC. Developer Slightly Mad Studios continues to work on a Wii U version, but it's been a tumultuous process.
Studio head Ian Bell recently discussed the topic on the game's official forum. According to Bell, "at the moment we're running at about 23fps on the Wii U." That's well off the pace of 60fps, the benchmark for other versions of the game.
Bell goes on to explain that 30fps isn't out of the realm of possibilities, but he also hopes for new hardware from Nintendo.
"We could reach a fairly solid 30FPS but it might take a hell of a lot of work," he said. "On the other hand, about halfway through us finishing, Nintendo might announce a new console (I have zero knowledge on this BTW but I've heard 'rumours'). Our work might just be the best thing that ever hit that new console in the driving sim genre."
Nintendo already announced that its next console will not make an appearance at E3 this year. Nevertheless, Slightly Mad Studios has no plans to commit fully to a Wii U release of Project CARS. Instead, they're "playing a waiting game at the moment."
