Ivory Tower and Ubisoft Reflections are "aiming for 30 frames per second locked" with the PlayStation 4 and Xbox One versions of next year's open-world racer The Crew, creative director Julian Gerighty has told VideoGamer.com, stating that a higher frame rate would be unrealistic given the size of the world.

"We've never been at 60 frames per second," Gerighty told us during a gameplay presentation this morning. "We've always been aiming for 30 frames per second locked. Today, unfortunately certain PCs have been overheating, so we're having frame rate drops. It's a hardware issue, not a software issue.

"60 frames per second is, of course, what we would all like to obtain," he continued, "but it's such a big world, and with all the online features running, it's just not realistic to obtain that. 30 [frames] locked is really, really good and exactly what we've been focussed on."

Despite being co-developed by Driver: San Francisco studio Ubisoft Reflections, development on The Crew is being led by French studio Ivory Tower, comprised of ex-Eden Games developers, which has created a proprietary engine for the next-gen racer.

"In fact, no," Gerighty replied, when asked whether The Crew was running on a modified version of Driver: San Francisco's engine. "It has the DNA of both Test Drive Unlimited, which was the world of Hawaii [and] seamless online, because it was conceived by Ivory Tower in France who are ex-Eden Games [developers]. But... this is a multi-studio project, so when Ubisoft asked Ivory Tower who [they wanted to] work with within Ubisoft, there is no better team - maybe in the world - for an action driving game, than working with Ubisoft Reflections. So Ubisoft Reflections are working hand-in-hand with Ivory Tower.
