Just installed Thurstmaster FF wheel today, borrowed from
a friend.. Will probably buy it, seems to be a lot better on GPL
than the Thurstmaster non-FF wheel I had been using.
Did copy settings from Eagle Woman's GPL page, (mentioned
below), which I reckon are not specific for the Thurstmaster FF.
Does anyone have a proved setting for thurstmaster FF wheel:?
Thanks for advising
From a GPL beginner
[Joy ]
allow_force_feedback = 1 ; Use FF
force_feedback_damping = 5.000000 ; damping coefficient
force_feedback_latency = 0.020000 ; latency (secs)
max_steering_torque = 330.000000 ; torque = max force
well here's mine,
force_feedback_damping =130.000000
force_feedback_latency = 0.0025
max_steering_torque =130.000000
but from what i understand there are alot of things that can affect
these settings.
like where you set your linear/non-linear slide bar. (mine is just
left of center)
it will take some experimenting, but one thing!
only change one setting at a time, and i seem to recall having better
luck if i power it off and back on, after each tweak.

force_feedback_damping = 2.000000
max_steering_torque = 200.000000

allow_force_feedback = 1
force_feedback_latency = 0.0045
force_feedback_damping = 130
max_steering_torque = 200
It seems that we're all using quite different settings. Different hardware
set-ups probably make a difference and so do the device gain settings. I
even had to adjust my settings after moving to Windows 2K from Win98SE.
I worked out my settings by following the instructions in the below post
which I found most useful.

GRAND PRIX LEGENDS AND FORCE FEEDBACK: A PRIMER IN CORE.INI SETTINGS
I believe GPL core.ini FF settings are extremely specific to your wheel,
your machine, and even your car setups and driving style. However, I also
believe that there is a logical approach you can to take to individualizing
your settings. With a proper understanding of what these settings do you
can produce realistically subtle tactile feedback that will enhance your
driving ability. To that end, let's take a look at each of the FF core.ini
settings, shed some light on what they do, and discuss some practical
approaches to setting them in a way that works for you and your setup.
LATENCY:
This is essentially how far into the future (in seconds) the GPL software
predicts what forces will be needed and sends them to your wheel, thereby
overcoming latency. I determined the latency setting by driving over curbs
repeatedly and adjusting the value until all four wheels produced individual
FF effects in sync with what I was seeing from an outside view of the car.
MAX STEERING TORQUE:
This is an interesting one. This is not actually the maximum torque your
wheel will produce, but is instead the *THRESHOLD* at which your wheel
produces it's maximum force. Let's just pick some numbers out of the air to
illustrate the point. Let's say the GPL software models the torque of
shifting at high revs at 50N, fish-tailing through a corner at 200N, and a
complete wipe out at 300N. If you were to set your max steering torque
threshold at
"50" all of these effects would be equally powerful as all would produce
the maximum amount of torque possible. So if you set this threshold value
too low the car is virtually undrivable and there is little distinction
between the various forces. If you set this threshold value too high (say
2000), you'll lose all steering torque altogether as no steering torque
force will ever reach the threshold necessary to trigger maximum effect. In
this example, setting the value to 300 would allow you to feel a marked
gradation between these 3 very different effects.
So how do you set this for your system? First set damping in both the
windows controller panel and the GPL core.ini to 0. We don't want to mess
with damping right now. From a dead stop turn your wheel to full left or
right lock, take your hands off the wheel, and then gradually accelerate.
If the front wheels (and steering wheel) do not center under forward
momentum and your car continues in a perpetual circle, then the threshold
value is too high. If instead, the wheel suddenly snaps to center and or
see-saws violently, then you have the threshold set too low. If the forward
momentum of the car very gradually brings the front wheels (and the steering
wheel) into forward alignment, as you would expect in a real world car with
manual steering, then you've got the threshold value just about right.
Adjusting the threshold to a level that just barely produces a centering
effect at low speeds will result in a very drivable car and nice subtle
tactile inputs that will cue you as to the status of your vehicle. Now here
is the part that really throws people: the Max Steering Torque threshold
*ONLY* affects *STEERING TORQUE FORCE* or the forces related to engine
torque, torque caused by maneuvering through corners, wheel centering
torque, etc. It does *NOT* affect any of the forces related to crashing
into guardrails or driving on grass. For some odd reason, known only to
Papyrus, these latter type of effects are only affected by the damping
setting.
DAMPING:
This, contrary to some reports, does in fact do what it says. It causes
increased "friction" or "viscosity" in the movement of the wheel and
therefore also tends to lessen some FF spikes. But here's where it gets a
bit strange. You'll find that as you increase the damping value, and the
friction on the wheel, you also increase the forces felt when driving on
grass or slamming into rails. I recommend adjusting this value just high
enough to barely feel a subtle difference between pavement and grass when
one single wheel drops off the road. Using this as a guide, you'll be able
to tell with your eyes closed if all four wheels are on the road. Hitting
curbs will feel realistic, guard rails will give you a jolt (but usually
allow you to correct), and the wheel will not be so tight that you begin to
lose torque effects.
The key to good driving and useful tactile information is subtlety in each
of these FF settings. Remember, GPL is not an arcade game!
Finally, in the Windows controller panel, I personally have Force Effects
set at 100% and dampening effects to 0% (you've already adjusted dampening
in the GPL core.ini so adding more damping in the controller panel will just
result in reduced less subtle effects). I like to use full linear steering
in GPL with a steering ratio of 15:1. These latter two settings are purely
a matter of taste, but you should keep in mind that they may effect the way
you feel the forces at work in your wheel or at least the way your car
responds as torque is placed on the wheel. Once you find a car setup that
suits your driving style you may want to tweak the core.ini FF settings to
match your setup.
Hope this helps.
