Although I have long been a fan of cockpit view, I am using it less and less in GT5. In the quicker cars, the higher FPS and frame stability is very obvious with the bumper cam, to a point that I feel disconnected and lost some sense of speed when I jump back to premium cars. In cars like Zonda R on a wet suzuka or Madrid/Rome, sometimes the frame drop is close to unbearable, so I am using it less for performance reason....totally didn't expect that.
