Bought myself a DFGT not long after it was released, and while it took me a few days to get the hang of, I don't see what the big deal is. I have mine set at 10 (max) force feedback, and wish that it could go up to say 50...but I must also add, that when driving the X2010 I have to turn it down to 5. For some reason all the "real" cars in the game, road or race, seem to have power steering or something turned on, when in the options it is all set to off, and simulation. But then in the X2010 I need tarzans grip to keep the wheel in my hands.
Sure I notice the left/right movement when driving in a straight line, but I think the best way to solve this issue (if its a problem) is to hold the wheel as close to the zero point as possible. Using your fingers against the base of the wheel's main structure, while holding the wheel with thumb/palm works for me when in the X2010.
But with regular cars its like driving whilst aquaplaning in real life. Barely any force restricting the turn of the wheel. And before you say, I dont have a great deal of upper body strength...
One thing I do think is bad programming is the lack of actual feedback. Once I turn the wheel past the point of max lateral grip, there should be a fairly steep fall in turning resistance, and getting to the maximum, point the force required should increase. Maybe I pulled the short straw, and something is amiss, but I feel like there is just a constant resistance force the whole way around the wheel. The only time there seems to be any change in resistance is when hitting bumps or riding kerbs.
It is for this reason that I have returned to playing with my trusty 6axis, somehow it gives me a greater "feel" for what the car is doing, despite having even less "feedback".
On other games however, I have no such problems...DFGT all the way!
