Another WTF for GT5 was me trying to get the head tracking working. I have the camera going through a USB hub and it appeared in the options settings, after i switched it back from the Moves wide angle mode, but i could not get the bugger working in the Arcade/Practice mode. After some reading on the intarwebs and frowning at all the conflicting information about it only working in some modes with certain cars i cracked it. In anything above a Beginer you have to turn off Fuel/Tyrewear in the pre-race options! don't ask me why, you just do. After i did that it seems to be working fine with all in car views.
The angle of turn isn't huge, it allows you to check out your rear view mirrors and look up and down a bit but it's enough to create a feeling of driver movement, i never realised just how much i do turn my head while driving in a game until now.
I've also been playing Tumble with my new wavey stick, does the end have to glow magenta? :D it shows off just how versatile the Move controler is and i imagine after a few more shots of JD stacking things on top of other things will be as much fun as:-
