I've spent ages trying to get the DFP to work. The G25 seems to have more success, I don't know why.
The problem with the wheel is it's not responsive enough, you can't change direction quickly enough (maybe the G25 is better for this), and if you tweak it, it still behaves like a controller joystick compared to a wheel. I can never get as fast as I can with a 360 pad. I think the arcadey fashion which is required of driving (to be fast) does not lend itself to the smooth movements of a wheel.
Yeah i agree with that. What i did to try and overcome that was to adjust the degree of rotation in the logitech profiler, so you had to move the wheel less to get the same effect. But still like you said, the wheel is probably more suited to sim type games
