GPL is giving me major headaches.  First, no matter what I do with
core.ini, I cannot get rid of the spikes in the force feedback that I
posted about a couple of weeks ago.  They seem to happen every time I
lift the throttle, and they are getting worse.  Normally this would make
me think that it's a controller problem, but GPL is the only game in
which it happens.  Surely someone has a solution to this?!?!  It's
getting to the point where I can't get decent lap times, because it
spikes when I am downshifting into corners and throws me in the ditch.

Secondly, I am convinced that the lap timer is wrong.  For the most part
the numbers make sense, but many times I have gone into the ditch, got
back out on the road, and completed a lap and then gotten a better lap
time than any of my clean laps.  This makes no sense!  I have heard that
there is a fast CPU patch available, but I thought it was only for 1.7
ghz or higher.  I am running a 1 ghz Celeron.  Theoretically I don't
need it, but I wonder if it would fix the timing problem.  Has anyone
tried the patch on slower machines?

TIA,
Hal

That's strange... perhaps it's more to do with the general settings of your
controller. I've found that I need to change these settings from game to
game to maximize the benifit from their internal settings. For GPL I suggest
getting rid of centering spring altogether, have the overal force setting
nominal, the spring effect setting at like 75-80% and the damping at about
34-40% and make fine adjustments through the settings in core.ini (are you
sure you're editing the correct file, BTW, because of Windows default
behavior of hiding extension for certain filetypes a lot of people end up
editing core.ini.sample instead of the actual file). If the effects of the
FF really continue to throw you off course, I suggest increasing the
"overall" damping setting and maybe introducing some centering spring to
help keep the wheel straight under braking.

Nothing wrong with GPL's timing and no patch is required for CPU's < 1.4Ghz,
it's just you need to realise that, true to the era, you're being timed by a
virtual guy with a stopwatch, not a TAG-Heurer timing computer. In places
where you're pitboard guy is stationed along start/finish this manual timing
method implies the time shown to you on the board is that of the last lap
you completed, not the one you're on and about to complete. Only exception
is the Ring, where you're signaller is on the straight following Sudkehre
and receives up to date lap time information via radio from s/f.

Haqsau, reading from the replies of your previous post on this problem, I
would agree with JS's post on the bad potentiometer as being the source of
Jerky wheel in GPL. From my experience of this, I have found that GPL is
very fussy about a dirty pot.

It is really annoying as that like in your case it doesn't appear in any
other game, Nascar 2 & 3, Need for Speed 3, 4, & 5, and numerous Motorcycle
racing games. Constant recalibration of the windows game control panel,
deleting the controls.cfg file in the player directory, recalibrating the in
game calibration every time you start GPL would only be a band aid for
awhile. I would usually end up replacing the pot about every month or so
depending on how much I would want to race GPL without this annoying
problem.

Brand New Pot = smooth GPL racing for several weeks. Long ago I read of
people cleaning the pots, but due to the low price of pots and the amount of
time to R&R them, I would always put a new one in.

Granted I've only had experience with analog (Thrustmaster) controllers, and
the incompatibility of FF with older games has kept me purchasing one. No
really I'm just an "Ole Cheap Bastard" ,,,,,,,, he he

Nascar 4 has had the same problem with my new computer and a Logitech
wingman Joystick, GPL game engine?
I have found that assigning IRQ's for all the PCI slots in the motherboard
bios (ASUS) instead of the AUTO selection gave somewhat of a cure, but
didn't make that jittery wheel disappear, just went from a major jerk (into
the wall) to an annoying but manageable problem.

I don't know how hard it is to get to the steering pot on your Logitech FF
GP wheel, but it may be worth taking a peek at.

Good Luck, and give Logitech a call.

Jan,

Thanks for the thorough reply.  I am not using a centering spring in
GPL, but I will try playing around with the other global settings and
see if that helps.  I do have the correct core.ini, I turned off that
silly "hide extensions" feature long ago.  ;o)

Thanks for the explanation of the lap timer thing.  It took a minute to
figure out what you meant, but I think I got it.  The thing that was
confusing me was that you get a lap time displayed the second time you
pass the pitboard, which made me think that was the time for the first
full lap, i.e. the one I was completing as I passed the pitboard.  But
if the timing is based on the start/finish line rather than the pitboard
location, I can see how it would have to be one lap off from that.  That
cleared up a lot of confusion!

Regards,
Hal

It is behaving exactly like a bad pot, but the reason I doubted it is
that not only is the problem not showing up in other games, but also
when I look at the raw readout in the calibration routine in either N4
or GPL, I do not see any spikes.  Also I thought N4's FF implementation
was similar to GPL's, but I get no spikes in N4.  Anyway, I guess the
only way to figure this out for sure is to dig in and look.  Thanks for
your advice.

Regards,
Hal

: It is behaving exactly like a bad pot,

FWIW, I got this with an old InterAct V3 wheel *and* a brand-new LWFF...
it's not bad pots in my case.

I see Jan answered your question about the lap timing in GPL. As for the
spiking in your controller in GPL try setting your front wheel cambers as
close together as possible  ie. Front Left  -0.25  Front Right   +0.25 or
similar . Try to avoid big differences between the two. This stopped the
spiking for me with my LWFF.
Sid.

A spikey pot is difficult to see. When I had a similar problem, eventually I
gave up and replaced the pot in desperation, and it cured the spikes.

It's not that bad a job, so it's worth a try. If it makes no difference, you
can always put the original one back.

I had a similar problem with a Thrustmaster USB wheel non FF, however it
only happened online. I traced it to being the USB port sharing an IRQ with
my ISDN card.

Some remarks are thrown in below.



Must be something about the dead-center or so.

According to my experience the pots give you problems earliest after one year.
This is for extremely extensive use (says my wife, I would call it regularly)
and a very humid and warm environment.
Unluckily you cannot get Logi-spare pots on the market :-(

Jens, you are saying then that I can't just run down to the local
electronics outlet and find an equivalent pot?  What is unique about
them?

Wouldnt depend on the quality of "pot" at ur local outlet?
oops wrong "pot" sorry :)

I think that kind of pot doesn't give you headaches, it just makes you
hungry.

I guess you must run very far. If you find any, buy 100 and offer them here.
Problem is
1st: the quality, but the original logi-pots were lousy too
2nd: the milled flattend shaft, this shouts for DIY.
3rd: those tabs (flaps?) at the pot housing. normal pots don't have them. No big
problem, since hotglue is your best friend :-)

BTW: Mike Turner from UK found the manufacturer (who makes these thingies for
several controller producers) and got even a quotation. Price was good, but
minimum purchase 1000 pcs.
