I just don't agree that you can just look at some code, and say, well this
is realistic when it comes to simulating a specific automobile.

It's pretty obvious that while DGF say RC2k has physics as complex GPL. that
there are so many things that are not correct about the modeling that throws
it all off. There a few things in GPL that are IMPLEMENTED wrong that most
anyone can notice. NFS:PU apparently has physics as deep as GPL, but when I
go b;asting though the course with my tires off the shoulder half the time,
it just isn't realistic anymore. When I can wreck like I do in that game and
keep going without a hitch, it's just not realistic.

I'm not looking for who can put down the most useless code in 9 months, I'm
looking for the game that gives me the most realistic driving experience.
Which is what racing is all about. You the track, and if you have to pass a
guy, then you do it when you get there, then back to the track. That's the
true beauty of Formula 1.

he's just being a jerk DGF makes non-sensible conclusions all the time. He
thinks that if Schumacher can do it, then you should be able to do it out of
the box. Despite the fact that maybe Eddie Irvine can't do it.

um no one said that the framerate wasn't effected by the graphics, but that
it is effected by both graphics and physics.

I don't think so!  Such a concept would be so stupid, it'd be
laughable.  But on the other hand, any user-modified or user-distributed
add-ons for *any* program under the sun would be illegal under the
definitions you were putting forward.  Way out of line with reality
too...

<Psssst, hey Buddy.  Got a bunch of cool modified GPL 3do files here,
free for the taking.  Want some?  Oops, the Coppers!  Let's scram!!>

Think it's a draw.

I actually did that, but the AI have troubl driving such more responsive
cars.

You can download the

http://www.uni-mb.si/~ucamtpgvn/VehNew.zip

file and unzip it into your Season00/Vehicles folder. To restore the old
values, use

http://www.uni-mb.si/~ucamtpgvn/VehOld.zip

But, as I said, these settings rather confuse the AI cars, and this is
for two reasons. At some corners the AI cars take a too aggressive line
and spin out. Secondly, the physics engine seems to be running at a
slower rate for the AI cars than for the player, and this may cause
certain instabilities in their cars calculations.

Some of this can be cured by modifying the setups that the AI cars use,
but i haven't found a satisfying solution yet.

So use those files only to get a good feel of the car, but for offline
racing use the old settings for now.

If you could really look at the code you could tell immediately whether
something is wrong or not. Yet we do not have access to the code. But we
do have access to data files that use that code in F1 2000. These give a
very strong clue as to what is modelled, and the car responds exactly as
it should to changes in these files.

As I said already in this thread, here I have to disagree with DGF. I
tried the RC2000 demo, and the car there does not respond as a rigid
body with mass and inertia should. Perhaps the release is different, but
form what I've heard it probably isn't.

As for GPL, not only is the physics engine superb, but I've also tried
hard to see what is implemented wrong. I still am not sure I can say
with certainty that any aspect of the car behaviour is off. The only
thing that comes to mind is that perhaps the camber changes due to
castor and kingpin angles on the front wheels are *perhaps* not
implemented, but I am not sure about that.

As for NFS:PU. The physics model is a vast improvement over the previous
ones, at least according to the demo I played. But there are some major
flaws that are not present in GPL and F1 2000. I have no ideas why this
comes about, but some physics aspects are clearly not very realistic in
NFS:PU. When your car gets really sideways, apply the throttle, and you
will straighten it out, for example. I think it is  the tyre model, the
modelling of the chassis inertia properties seems rather good.

That is why you can perform certain test to show that the modelling is
indeed as it should be. You see, modelling the overall behaviour of the
car as a rigid body is not that hard, and there is only one correct way
to do it. The F1 2000 car, just like in GPL or Viper Racing, responds
that way. I've played the demo of RC2000, and in there the car does not.

Trust me, when you see the physics parameters in .veh files you know how
they modelled it, there is really not much room to use this data in any
other way, and it shows in the sim. Either that, or at least I am as
unimaginative as to how to use the, for example, inertia tensor in any
other way.

actually I read off the High Gear web-site that the physics in the RC2000
demo are merely place holder.Which is a shame, because I'm not going to buy
if  I don't which parts of the placeholder physics are still there.

as for all this about physics modeling. I'd like to reiterate and add to my
thoughts on the subject.

There are 3 major thing that make a sim realistic. (to me)

1. The underlying physics code needs to be as dead on as possible. There are
a few aerodynamics things we don't really know, so close as currently
possible.

2. The vehicles being modeled need to be implemented with as much detail as
possible. I think one reason NFS:PU was so good, was because the
unprecedented access to the cars helped this area make up for most of then
shortcoming in area 1. This is actually a problem with modern F1 games, as
it is hard to get access to some important information on all of the cars.

3. All the information needs to be presented to the senses as best possible.
This includes a perfected***pit view, as many dynamic audio ques as
possible, including engine, tires and a spotter. (if applicable) Finally
proper force feedback is the best new hop for bringing us total car control.
