These values don't give too strong forces. If you want
stronger forces try the values I used before.

First, the windows settings are scale factors, not additive. Setting
damping to 100% in Windows doesn't add anything, it just gives you the
full value the game asked for. Setting it to 0% would normally turn it
off.
In GPL it doesn't work out that way because GPL doesn't use the spring
and damper force feedback model. Steering torque and damping are
apparently settings that GPL uses in its own internal model, and
therefore damping in core.ini has no relation to damping in the Windows
control panel.
Secondly I don't think you are going to get satisfactory latency values
by running over curbs. With a frame rate of 36 fps max, your resolution
on anything that you judge strictly visually is about 28 msec. For me
at least, I found it very difficult to judge whether I had enough
correction or not using that method.
The method in the GPL readme file works much better. Drive down a
straight at a good rate and swerve from left to right repeatedly. Do
this with a car that is set up with firm springs and shocks. Ideally
the aligning force on the wheel should change direction when you change
the direction of the wheel. There should be a very slight lag due to
the time it takes the vehicle to settle on the suspension, but it should
hardly be noticeable if you are using a stiff suspension. You know what
this feels like in a real car, it shouldn't feel any worse in GPL.
In my case, using the small latency values that most people recommend,
there was considerable delay between the time I changed the wheel
direction and the time I felt the force change. In fact I was often
turned completely the other way before I felt it. I had to increase my
latency value to 0.100 (100 msec) before it felt right.
This is only slightly higher than the Papy recommended value of 0.085,
which was based on the Microsoft wheel. Therefore I think my setting is
right for my crappy wheel (LWFFGP) and I also think that the 20 - 30
msec number that most people are using is too low.
This makes all the difference in the world to your ability to control
the vehicle. Before making this change I could not rescue the car if it
got a little sideways. I would just end up seesawing back and forth and
going wider each time until it spun. After making the change I can now
rescue myself from most mistakes. Before the change I kept going to
stiffer and stiffer setups to try and keep the car under control. After
making the change I have been able to go much softer and still control
the vehicle.
I've read posts in here from people who say they tried a force feedback
wheel with GPL or N4, and couldn't even make it around the track once.
They usually end up taking the wheel back. That was also my initial
reaction, and I am convinced that the problem is entirely due to the
latency number. Set it up right, and it feels right.
I have noticed that with high latency values the wheel makes a lot of
very small motions for no apparent reason. This is the drawback to high
latency, but can be minimized by reducing steering torque and increasing
damping slightly.
I really recommend trying this with either GPL or N4. You can always go
back if you don't like it. It makes a huge difference, and I especially
think that if you are using a gear driven wheel, which will have
naturally higher latency due to backlash, this is a must.
My two cents,
