Ian, the NASCAR3 FF seems not to be very well designed for the Logitech
wheel (and I asume for I-force FF in general?).
Usually playing it with a Saitek (Microsoft-FF technique), I tried it this
weekend with a Logitech and was quite disappointed about the FF.
Setting FORCE_DAMPING_PERCENT to '0' (which is set to 200 with the
Saitek)helped a lot, but I mainly miss the forces from the y-axis, which on
the Saitek can be mapped to the wheel.
The different FF-systems also have a different approach concerning the
centering spring. With the Saitek there is a strong centering force
implemented in the FF (still not as strong as you can get it in GPL or
Viper), while with the Logitech there is not. If you set your centering
spring to about 100% and enable the 'apply centering in FF-games' option you
get about the force as with the Saitek, but it seems to spoil the FF itself.
I liked it best with the centering force set to 65%.
Overall, the FF in NASCAR3 is great with the Saitek, sure it is by far not
up to par with GPL or Viper, but it's fun to drive with and I would give it
the 3rd place.
