Call of Duty: Ghosts was showcased on Tuesday at the Xbox One reveal which led to speculation that a new engine has been in the works at Infinity Ward. However, it seems like this is not the case. The engine isn’t completely brand new but neither is it exactly the same.
“When we’re talking about a new engine we’re talking about upgrading significant systems within that engine,” said Infinity Ward animation lead Zach Volker. “We’re not talking about throwing it all away and saying we’re starting from the ground up.”
He added that it would be “impossible to develop a new engine from the ground up in a two year cycle.” “What we do is we say, ‘okay what are the things that are significant and that we would say that are encompassing of the engine or its visual quality? Are those being upgraded in a significant way? Alright, then I think that warrants that we’ve got a new engine on our hands.”
