ICR2: Grip bug?

by Doug Reichl » Mon, 06 May 1996 04:00:00

Can someone please explain to me the grip bug in ICR2?  From what I have
learned, the bug is found when starting ICR2.  It will have low grip for
about 10 - 15 mins.  Then the grip will go to a 'normal' level.

I have found this since driving at Martinsville.  When I first start ICR2
I can only manage 116mph laps if I'm lucky.  Once I wait 15 mins, then I
can crank some great laps with my best being 135.432mph.

What's the deal with this bug?  How do you 'fix' it?

From what I've heard this bug has been found and will be corrected in
the patch due out when the Win95/Mac version is released.  Scheduled for
mid June release.  Wish I had known about this bug before I spent hours
working on a setup at Nazareth only to end up de-tuning my car
cuz I couldn't control it when I restarted ICR2.  Now it's back to
garage.  Damn, what a waste of time.  Oh well, I learned more about
setting up cars.

Whoa! I read this group regularly, and I haven't ever heard of this
bug! Maybe I'm missing stuff with all the Hawaii flak tripling the
posts lately...

If true, this is by far the most serious one I know of, and, depending
on it's magnitude, it could explain some extremely time wasteful
episodes (epochs!) of my own, and why I can only break my track
records after significant "warm up." I thought I was just sloppy
whenever I started racing! Jeeze...

Any more details on exactly what this bug is about? For instance, do I
need to be in a race for 15 minutes before the traction sets in? Or
can 15 minutes of sitting in pit lane for a "practice period" free me
up from the bug? How about in preseason testing- what is the procedure
for "warmup" there?

When was this bug discovered?! If there really is a bug, I am very
happy it was discovered, because that is a very subtle one that many
drivers would be likely to blame on their own driving.

Yikes!

Can't answer your questions but I thought it was me yesterday.  I had
gotten a wonderful setup at Nazareth, was doing 189-190's with my
qualifying setup.  Took a rest and came back and spun out everytime I
took it out.  Even if I took it real easy on the 1st couple of laps.  I
was totally confused and went back and tightened up the car.  I guess
until it's fixed we have to pretend the rain washed the track clean ;-)

Hey are you sure it just isn't COLD TIRES.

: Hey are you sure it just isn't COLD TIRES.

That's what I thought at first also.  However, why was it that after
spending almost an hour I could consistantly go out on fresh *** and
do 189+ with my qualifying setup.  Then about 20 minutes later (after
restarting ICR2)  I couldn't keep in on the track doing the corners at
130+ mph.

Nope, it's a bug for sure. Try running the QUAL setup at Phoenix and see
how often you spin into the last turn. Now hit Shift-R a few
times....whoops!....it's gone! The car suddenly changes from massive
oversteer to pronounced understeer with no setup adjustments.

How often does it rain in Phoenix... ;)

Cheers!
John

OK- exactly what does it take to get past this bug, restarting it a
few times, or letting it sit for 20 minutes?

Or letting it sit for 7 more months waiting for the patch?

This bug is very evident in the N. Los Vegas track. you have
severe underster and then severe oversteer without any gradual change.

Try taking the dogleg at talladega. you gota take the exact line at
first, 15 min. later you can make a turn  with 2 other cars using almost
any groove

Rick, you've generally given us the low-down on bugs-- could you
please give us a few details on how we can work around this grip bug?
For instance, can we just let the car sit in pit lane for 20 minutes
in a practice, or must we race for 20 minutes? Or can we beat the bug
by restarting a few times as some people have suggested?

Thanks!

There is no "workaround" for this bug. The bug is that the weight
distribution on the tires gradually shifts as you drive. The bug is fixed
in the upcoming patch and Windows 95 and Macintosh versions.

Hi Rick,

I hope you're testing the Win95 patch with the Thrustmaster T2
steering wheel. I have two Win95 racing games and niether one works
with the T2 (even though the T2 configures correctly under the Win95
Control Panel joystick option). You *cannot* depend on the Win95
calibration and assume that if it works with that, it will work with
your game.

I always assumed that this had to do with the spread of the numbers in the
DRIVERS2.TXT file...but it would explain some stuff.  Does this bug affect
every copy of ICR2?  

In a modem game, could one player to be affected, and the other not?  I often
find that I don't have as much traction in a modem game as when I'm running
standalone.
