  I am probably the only one here that will agree with you on this one :-)
This is caused IMO by the data the tire model in GPL uses.  Peak force slip
ratio is around 20+%, rather than maybe 10% or so.  The slip angle curve is
pretty far out of wack too, although the peak forces generated are probably
about right (hence cornering speeds are probably right, but you'll be "sliding"
at a larger slip angle than you probably would in the real cars.  I'm not sure,
but it's quite possible that other sims have this data more accurately
estimated.  In other words, the GPL cars drive like their tires are extremely
soft.  This will cause exactly the kind of difficult feedback and "unnecessary
translation" you've been talking about.  I've tried it in my sim too.  Setting
the peak force slip ratios and angles to high levels (like GPL) causes
unpredictablility just as you've described.

  I can't say why the sense of relative speed is prefect because I haven't
played CPR or GP3 (I'd bet it's FOV choice).  However, the tires probably feel
more alive and easier to anticipate because GPL's lateral and longitudinal
force curves appear IMO to be exaggerated along the slip angle and slip ratio
axes..  That means the tires act like they're too soft and squishy, basically.

who's wrong... the world? or you?

"THE WORLD!"

It wouldn't be the main reason of course, but it won't help either.
Ignoring the obvious lack of g-forces etc, with a video camera
the low resultion will be a much bigger problem than the framerate,
especially since the need for high frame rate increases with
resolution (and hence decreases with low resolution.)

(*)  Actually it is often easy to see stutter when watching a
     movie. It seems to be most evident in slow pans filmed
     in bright light (motion blur hides stutter, maybe bright
     light scenes are filmed with shorter exposure times, thus
     reducing the motion blur?)

It's the shutter speed that makes motion blur, but anyone familiar
with a camera knows that the 1/24 second speed needed for a perfect
motion blur is still a too long exposure time. Then again, maybe
cinematic film needs longer exposure that the familiar 35 mm single
picture camera ?

The V5 got hardware motion blur, sadly, no game uses it, and none will
:( Do the GeForce3 have this capability ?

anyway; stuttering in computer games is often caused by double
frames.  if you have:

a) an animation running at a constant, solid 30 fps
b) an animation running at 100 fps, but the computer can only barely
   render fast enough, so you see two identical frames ones a second
   (because the computer can't keep up)

then animation a will look smother.

hardly, but you can't compare real-life footage and rendered images
like this.  or you can compare them, of course, but they're quite
different. :)

sure, but who says the exposure time has to be 1/framerate?

IIRC=if I recall correctly. :)
Problem is that EYES have 170 degrees of vision, but the monitor in
front of you is only ... degrees wide in that view. So there's
problem; in a real car you can see more (if not wearing a helmet ;-)
).
170 degrees in your sim looks ridiculous since it's in a 20-30 degree
view when sitting behind your computer.
Although I must add FOV sometime since it has a great effect I think
on sensation of speed and is dependent on the person and the distance
that he/she's sitting at.

But it's quite obvious that the exposure time can't be longer
than 1/framerate leaving us with the possible range from zero
to 1/framerate.
