GPL: FF latency - please explain

Hello,

I'm experimenting with the FF settings in GPL's core.ini and notice a big
difference in feel whilst changing the latency parameter.

Since I don't really understand what this latency parameter stands for could
somebody out here shed a light on the 3 ff parameters (damping, latency and
torque) used in the core.ini?
I did notice that decreasing the torque-paramter increased the force felt! Is
there some sort of information on how those parameters are translated to the
steering wheel?

Thanks,

Jan.

The latency is the delay for the FF effect before it kicks in on your wheel.
Give it a high value (0.500) so will you se. There is always a very little
latency in games before you can see what happens on the screen. To get the
FF in sync with the action on screen do you need to adjust the latency.

I think the default value for latency is good in GPL.

I hope you understood this, because I dont. :)

JAN it's very well explained in the readme provided by patch 1.1:

"Generally, the lowest number that works for you is probably best.  Try
0.0, then move it up if the force seems out of phase"

That means : increase the number until the force are back in phase.

On my LWFF i'm using .210 , if you go to high in numbers, you'll have
unwanted spikes. If you go at 0.000 , with a LWFF, there will be lag
between what you see and what you get.

I have done an elaborate setting guide about the LWFF at

http://www.simracingmag.com

Check under SPY's corners :)

I am using 00.000 and noticed that I have a proper response.
I have a P2-450 and it may make a difference.

Hello Mauritz,

Thanks for your explanation. Let me see if I get it right (so I can explain it
to you :) ):

So if I understand this well this latency number is a delay to keep your
graphics in sync with your steering wheel.  If you set it at zero (seconds?)
you'll notice it immediately in your wheel before it actually is visualized, am
I right? So this latency number is heavily dependant on what system you're
running GPL on?
