Perfect Dark was ported by 4J Studios , the same studio that previously developed the Xbox Live Arcade versions of Rare 's platform games Banjo @-@ Kazooie and Banjo @-@ Tooie . According to Microsoft Game Studios creative director Ken Lobb , the development team " took the original code , ported it to the Xbox 360 and included deep [ Xbox Live ] integration . " The game was developed over a course of approximately 11 months after the creation of a working prototype . As the Xbox Live functionality had to be written from scratch , the developers opted to completely rewrite the game engine rather than do a port through emulation . As a result , although the game play exactly the same , the code and renderer is different . The game also run at 1080p and 60 frames per second .
