Speaking on Twitter in response to fan questions, DICE's Johan Andersson said: "We always do 30 fps on consoles, not possible to fit in vehicles, fx [effects], scale and all players otherwise."
As IGN reported last week, Battlefield 3 was shown running for the first time on console on Late Night with Jimmy Fallon. You can see the demonstration below.
Infinity Ward and Sledgehammer, meanwhile, have consistently claimed that Modern Warfare 3 will never dip below 60fps.
How much does framerate matter? Does the promise of double Battlefield 3's framerate give Modern Warfare 3 an advantage over its rival that it didn't have before? Or is it ultimately an irrelevant specification?
