The engineers at Digital Foundry have used GT5 Prologue to demonstrate one of their new video performance analysis tools.  As you can see in the clip above, their software graphs the frame rate at a given point in time while marking each torn frame.  They cite all of the criticism that the game has received for “tearing”, yet their objective results show the game performs exceptionally well.  Another revelation: frame rate is cut down to 30 FPS during the “pre-race drive-by”, with lots of torn frames.  Once the player gets control of the car, the game rockets up to 60 FPS, with no obvious explanation.  Watch how the FPS is, otherwise, only really affected when  other cars are in very close proximity.
