GPL - Driving with two feet?

by wtonsm.. » Wed, 05 Apr 2000 04:00:00

Having heard about trail-braking, and always anxious to shave another
second off, I decided to give it a try.

First of all, I had to convince my force-feedback wheel (LWFF) to use
different axes for brake and throttle instead of sharing one. (See the
thread - LWFF - Separate axes)

Now, finally I am ready to give it a try.

Well after just a few laps at Silverstone, I am not up to my personal
best (1:32.55), but did manage a 1:33.36, not bad.

I will admit it is awkward at first, and I have by no means mastered it
yet. But the thing I like about it most is, it gives you the ability to
more smoothly transition from brakes to gas coming out of corners.

As any good GPLer knows, the speed you come out of corners is much more
important than the speed you went in at.

As a one-footed driver, you have to stop in a straight line as much as
possible, sort of slide through without any throttle, then feed the gas
back on. In the heat of the moment, it is all too easy to jam the gas
back on too abruptly, and induce wheel spin out of the rear end. This
is the last thing you want in a corner you are already sliding in.

Not to mention, the weight transfer. When you are under braking, the
front tires are heavily loaded. If you suddenly lift off the brakes and
jam on the gas, you are causing a significant weight transfer to the
back end, again, just at the worst moment.

With the two-footed approach, you can manage you rate of braking with
one foot, and help keep your car stable through the corner by leaving
slight braking pressure (trail-braking) on as you feed the gas back on.
Also, you can keep your revs up.

The result seems to be a much more smooth transition from flat out,
through braking, turning in with gradually reduced braking, easing gas
back on with trail braking, and flat out again. The chassis is not
subject to *** jerks in mid-corner. And my LWFF is not "bucking"
nearly as much.

This is only possible with the high-fidelity physics model of GPL. You
might find it of little benefit in "lighter" sims. But in GPL, if you
ask around, a lot of the consistently fast drivers (not necessarily hot-
lappers) use two feet.

Give it a try.

Cheers, wtonsmann

I think you will find you are also faster into the corners if you can
master the technique of turning in before releasing the brakes.  Begin
to turn in - ease off the brake gradually as you turn - add a bit of
throttle if it wants to spin.  Done perfectly, there is a seemless
transition from braking to on-throttle.

You can trail-brake with single axis. If your feet are quick and smooth
enough there really isn't much difference between using dual or single
axis. Having a good neutral setup helps as well.

I agree.  It's the only way through Aquae Minerali for me! (in F1-2K).  
I am trying to make it work in Tosa as well, but I'm still learning!

I had to convince my force-feedback wheel (LWFF) to use

I just got one myself, and mine worked just fine out of the box - I can
brake and gas it at the same time, and I didn't have to take extra steps
to get that working.  Forgot what the settings in Game Controllers say
(I don't have the wheel loaded in this OS at the moment).

there really isn't much difference between using dual or single
when i changed from single to dual axis, the difference was night and day.
you must have something wrong with your input device.

There is a difference, sure. But personaly I don't see much difference
with my times when driving with 1 foot or 2. I can trailbrake or balance
the car just as well with 1 foot. Everyone is different I guess.
I'm not saying that there is no difference in the way Dual and single
axis work, there is a big difference.

Ah, my bad then. I agree that "times" might not be improved right away. In
fact, my times slowed at first, but now that I'm used to the new feel I have
set PB's at all my tracks!

Yeah i drove single axis for a few days its was ***y awful..I always use
left foot braking mid corner etc, as this gets the nose to bite and stops
under steer also using this technique i can go into corners much faster and
have far more control on the car limits...


daul i could hit high 23's...race cars are driving with both feet, heel and
toe or clutch less...a modern F1 driver that uses one foot for each pedal is
the faster driver...It cannot be siad it isnt faster..you tried driving a
kart with one foot???...Slow as hell you need to use them both at once, same
