Thanks for checking man. I was kind of getting used to that deadzone in most games (kind of slow/simulation) but then I tried some arcade ones, like Underground - the arcade dump, and it is so tricky to handle, as that deadzone is just in the way doing nothing and if one has to turn multiple times in a matter of seconds... the car just doesn't follow quick enough!!
I forgot if real driving wheels in arcade machines have this behaviour, but I don't remember it at all, so I doubt it?
I feel tempted to buy another brand (not logitech) to give it a go... but if the deadzone problem exists in all of them, it might not be worth getting a new wheel just for checking this behaviour...
