Consoles only offer a finite amount of resources, and developers utilize various tricks to get the results they want. For example, Bungie noted that a drop in vertical resolution in Halo 3 offered them increased bandwidth for improved lighting effects. Dropping the framerate would allow Insomniac -- and other developers -- to increase the amount of detail in each frame, something the studio is seriously considering. "There is virtually no advantage in sales or reviews of a 60 fps game versus a 30 fps game," Acton notes.
In fact, in some cases, a lowered framerate actually makes a game look better, Acton explains. "A drop in framerate is interestingly seen by some players as a reward for creating or forcing a complex setup in which a lot of things must happen on the screen at once." We nickname that phenomenon the "Otogi 2 effect." With all of these aspects considered, it seems the studio will no longer focus on locking a 60 fps rate. "It means that framerate is still important to us here at Insomniac, but it's not on the same pedestal it was before. And that Ratchet and Clank Future: A Crack in Time will probably be Insomniac's last 60fps game."
