The Xbox One version of Forza Horizon 2 will render natively at 1080p and run at 30 frames per second.
This is in contrast to launch title Forza Motorsport 5, which ran at 1080p and 60fps.
"I think what we did on Horizon was demonstrate that, and this is really important, a locked frame rate that's absolutely solid and never drops is the most important thing for our game," Playground Games creative director Ralph Fulton told IGN.
"I think I remember that's always a hot-button topic, until a game comes out and people go, 'Oh, this actually really works'. But 1080p was an absolute must for us, it's the benchmark for next-gen."
Asked why Horizon 2 will be locked at 30fps whereas Forza 5 was 60fps, Fulton replied that it was necessary because Horizon's free-roaming gameplay meant the console wouldn't be able to accurately predict and pre-load upcoming scenery in advance, something a normal linear racing game is more capable of doing.
"The biggest difference is that, obviously, we're an open-world streaming game," Fulton explained. "We need to be able to drive in any direction at up to 270 miles an hour, if you're gonna soup up a Veyron or something like that.
"So one of the big technical challenges that we had to face was making sure that we could stream in a world that is next-gen beautiful, but fast enough to keep up with the fastest car. That's a huge tech challenge but it's one that our guys just eat up."
Forza Horizon 2 was announced in early June, and is planned for release on Xbox One and Xbox 360 in fall 2014.
