Hi,

can someone tell me what this Damping setting actually means and what it
does? How should I set it up when my FF Strenght is 100%, Steering Linearity
100%, Latency 0%. I have search through web and found nothing about it.
Also, should I use Latency when playing offline or is it just latency for
online games.

I was going to ask the same questions. 100% linear setting with my Ferrari
FF wheel.

Hi guys,

damping forces are used to simulate anything that slows the steering wheel's
movement down. Like friction caused by the bearings, or by *** on
pavement, grass or sand. Or, in the case of driving in a sand trap or maybe
water or mud, to simulate the higher resistance encountered when steering
because the tire has to an extent sunken into the ground. There may be more
that I forget right now.

The ground-related damping effects are in general desirable as they tell you
what the car is doing, the bearings-related effects are only partially
desirable as they also blank out some of the feedback information that tells
you about the grip status of the tires on the ground - although they may be
realistic. But, in real cars you'll also try to get as low-friction steering
as possible.

If you set the Latency to higher values, sometimes it is useful to set the
damping a little higher as this way you can to a degree avoid the snappy
oscillations of the steering wheel that higher Latency settings can cause.

I think BTW that the 'Latency' slider should be called 'Latency Prevention',
as for all I know the higher you set it, the more the game tries to foresee
necessary FF effects, i.e. it tries to send them to the wheel a little
earlier to ensure that they are reproduced at the same time the on-screen
action takes place.

If you have a fast computer, a wheel whose drivers don't consume much CPU
time and that reacts quickly and in a subtle and detailed way, you don't
need much on the Latency slider. A very moderate setting will ensure you'll
get the FF in time, which allows you to react at the right time.

A potential negative side effect of this is that the FF precalculation may
induce oscillations to an extent. I've never really understood why this is
so, but I've tried it and have learnt that this is indeed how it works.

You can use the damping settings to smoothen these oscillations a bit.

With a 100% Linear setting (i.e. slider fully to the right) I'd say you
hardly need any dampening to prevent oscillations, as around neutral all
movements will probably be so subtle that they are easily manageable
manually. OTOH, I assume that for the same reasons, the damping effects will
be subtle as well, so you may have to try what works for you. Just make sure
you get decently subtle FF effects, i.e. you feel the ground, or when the
wheels start sliding, but also feel when the steering gets stiffer or less
stiff on changing grounds, or with speed.

If by 100% Linear you mean 'slider fully to the left', some damping can help
avoid the aforementioned oscillations, but again at the cost of some subtely
and detail in the FF effects, so try the same as described above - set this
high enough to notice what the wheels are doing, but low enough to get
subtle and detailed FF effects.

The new or old model David?

I use 99% linear setting, it would be at 100% but I always put in a little
safety gap in case (for what? I can't say it's always been like that for
me).  For NR2002 or N4 my force feedback settings are 50%/50%/45ms.  I find
those settings to be pretty good, it's just weak enough yet subtle.  On road
tracks, I'll lower the damping simply because it's a little too much.

In the Thrustmaster Properties section of Windows, I have 100% overal gain,
0% spring gain and 45% dampening.

I still haven't found the perfect GPL FF settings.  It's always too darn
strong, but when I make it weaker I loose all damping effects.  I simply
don't understand how to tweak the core.ini

The one with the silver pedals. Old model I'm sure. I'm just going to have
to experiment I guess.

Great description that I agree with.  For the record, I use 100% strength,
30% damping, 0 latency with Guillemot Ferrari on a fast system.
