In an exclusive interview with Xbox World Australia, Dan Greenawalt from Microsoft Game Studios has confirmed that Turn 10, the Forza 2 development team, has already achieved 60fps at 720p for the game's visuals:
"While it's never "easy" to squeeze in the high level of detail we have, the Xbox 360's power has made this an achievable target at 60fps and 720p with 12 unique, customizable and damage-able cars on track at once."
At the same time, Turn 10 has been able to improve physics even further:
"The increased power of Xbox 360 has allowed us to showcase our incredible physics engine to even greater effect. The physics will still be running at extremely high frequencies (180-360 fps)." explains Greenawalt.
"Some systems are now running even faster. We felt the bumpy nature of tracks like Sebring in North America required running the physics at rates we've never seen in any other game. I think the biggest change that most players will notice is the increase in the graphical framerate."
