Well ive had my dfgt for a couple of weeks now and have mostly been using it for iracing. I just got my ps3 back up and running and hooked up my wheel for the first time up to play GT5. Wow what a complete disapointment. Every car i used it felt like I have to correct the car due to having to fight the wheel. I took this video to show what it does on a straight away with a slight movement. The wheel feels like it moves all the time on its own and i have to fight it on every corner.
