According to Nicolas Guerin, the level designer for "Unity," the studio decided to go with 40 fps to preserve the quality of the game.

"At Ubisoft for a long time we wanted to push 60 fps," he said. "I don't think it was a good idea because you don't gain that much from 60 fps and it doesn't look like the real thing. It's a bit like 'The Hobbit' movie, it looked really weird."

"I think collectively in the video game industry we're dropping that standard because it's hard to achieve," Guerin added. "It's twice as hard as 30 fps, and it's not really great in terms of rendering quality of the picture and the image."

Like Guerin, the game's creative director Alex Amancio defended the company's decision to go with a lower frame rate and explained it's more suitable to the nature of "Unity," Game Spot reported.

"30 was our goal, it feels more cinematic," he said. "60 is really good for a shooter, action adventure not so much. It actually feels better for people when it's at that 30 fps. It also lets us push the limits of everything to the maximum."

The director then emphasized that these kinds of technical details are not that important as long as the studio is able to produce a top-quality game.

"It's like when people start asking about resolution," Amancio said. "Is it the number of the quality of pixels that you want? If the game looks gorgeous, who cares about the number?"
