being not a 'bad' gpl driver (128.68) round monza.

i thought i'd have a shufty at gp3. altho the graphics were
disappointing on voodoo 3 , framerate was ok thanks to the duron 900.

anyway i did a few laps on brazil, i remembered it quite well thanks
to my good laps on the amiga f1gp back in the early 90s.

anyway i found that i had something called steering help turned on,
which i was pissed about cos i like to race it as its supposed to be,
after i turned it off, i found that taking a corner which i feel
wasn't overly quick the car just spun, it was like there was NO
warning, i tried to correct as quick as i could but there was nothing
there.

is it really this hard to drive a gp car nowadays? or isn't it
realistic ?

any help/info would be cool, btw using default car setups

Don't know about anyone else, but after driving GPL and going to GP3 I thought
the exact same thing.  But after several hours of use, I did start to get a
"feel" for the car and was able to "catch" it, most times anyway, before it
took off on me.
In my case, my ability to feel the car got better as my brain came up to speed
on the very frantic pace of the sim.

Yeah, takes a while to get used to... FF is more detailed than I first
imagined.

Brazil is a bad example as there's some quite *** bumps in the corners
there (e.g. Bico de Pato), which call for the rear to be noodled up somewhat
(certainly from the default setup).

You make a good point about the pace of driving being quite frantic. While I
drive online GPL GP's *for relaxation*, I find GP3 races take a lot out of
me (and I'm just driving 60% distance). Very hard to consistently stay ahead
of the car.

you must realise that current F1s effectively do not have suspension...
pound that kerb and you'll bounce the car... if there's any power down when
you bounce, chances are you'll spin.

your driving line shouldn't be circular unless you're taking the corner at
constant velocity. as you brake increase the wheel lock as you approach the
apex (within reason, you shouldn't get too much rear end movement), and ease
it off as the power is fed in... with practice you'll get a feel for how
much. before long you should easily be able to place the car onto the ripple
strips going in and coming out.

on fast corners there is some margin for error... you'll generally feel the
front pushing long before the rear gets loose.... just ease back on the
wheel lock and/or throttle.. it doesn't take much to reel the car back
in.... of course, a big slide and you're gone.... when you're doing that
many g's round a corner and the traction really lets go, there's not much
you can do.

"your driving line shouldn't be circular"...?  Ok, I give up - what does that
mean?

your turn radius is directly proportional to your cornering velocity.... as
you increase speed coming out of a turn you need to decrease your wheel lock
to be able to get all the power to the road, and not spin the wheels.....
look at the way the drivers typically take a hairpin, they drive almost to
the outside of the track going in so that they have as straight an exit as
possible (crucial when you're trying to use all the engines power and don't
have much downforce at the lower speed).

I think he's talking about making the apex the tightest part of the corner
thus
getting higher entry and exit speeds, as opposed to trying to find the
largest
constant radius through the corner.

Does that help? ;-)

spot on :)

i thought i'd leave out the bit about the friction circle :o

I seem to always end up turning the wheel MORE at the turn exit, just to stay
on the track.  There's a flaw in my driving style that I can't seem to fix.

fix.

most probably because you're carrying a little too much mid-corner speed....
i'm normaly quite slow at mid-corner, usually two wheels on the inside kerb
to buy myself as much exit space as possible. it has the added benefit of
forcing the guy chasing to slow down, then you get the jump coming out and
don't have to worry too much about him getting a tow and taking the place
back.

Ouch I understand that problem.  Too much speed or a too early apex is often
the cause.  You could in GPL tweak with the clutches, or to loosen up the
car.  It's something we learn much on Stockcars, from N1 to N4.  Try to have
the wheel straight as soon as possible exiting a corner.  At tracks like
Dover, the effect is essential for a fast car. The mid-corner portion is
quite long, so you have to modulate the throttle to find the best moment to
straighten the wheel.

The guy who is fastest on the track is the one who has the wheel straight
more then anybody else!!!!!

Probably a little of both.  I've been 'conditioned' to believe that I have to
get through the corner as fast as possible.  Well, fast implies using the
accelerator.  So I end up stomping the gas as soon as I make the turn-in(which
is usually early).  In looking back, I can see this style has followed me
through N1 and ICR1 forward.  It's so ingrained now(I guess) that I don't know
how to break the habit.
