Complaints have been pouring in about Quake 4 for the Xbox360. The game suffurs from a very unstable framerate, and some users have experienced lock-ups and crashes. The game’s unstable framerates come as a surprise to many, especially considering how much better Perfect Dark Zero and Call of Duty 2 look. Many speculate that the game’s unstable framerates and poor performance are more likely to be a result of a bad job porting the PC version to the Xbox360, while others insist that it’s due to a lack of power with the Xbox360. Lockups and crashes indicate that the game’s issue might be poor programming, although you can’t rule out issues with the Xbox360 unit itself. More will be posted on this developing story as it becomes available.
