Nope; in fact, just the opposite - speed sensitive PS systems are mainly a
passenger car item. They increase boost at low speeds, primarily to make
steering effort easier for parking. Racing-type systems that I'm aware of
are linear in boost. The only implementation I can imagine where higher
boost at high speeds might possibly be useful is in F1, where there is
enormous high-speed downforce involved. Nascar does have downforce, but is
not such an extreme situation.
Nope again; I would suggest the increased downforce and inertial effects are
what you're feeling (and attempting to dial out). The same happens in the
ISI F1 sims at high speed if you don't use an aid to minimize it - you can
easily feel the steering load up on long straights in F1C.
either.
Your point about joysticks has some relevance here. As I noted before, the
speed-sensitive steering in games/sims doesn't directly affect the forces at
all. What it does at say, 50%, is to simply reduce your steering input
gradually as speed increases so that at top speed it's reduced by 50%. So
20 degrees of lock at your wheel would only be interpreted as a 10 degree
turn at top speed (or whatever speed the game brings in the full effect).
It does make the car feel more settled, for sure and means you don't have to
be as precise in your driving. As I also noted, it's basically a help
function. And it's primarily left in to accommodate users with marginal
controllers (like joysticks, or even cheap wheels with a narrow rotational
range) who might otherwise find the game too difficult to control if they
run enough steering lock to get around hairpins. As far as reality goes, as
of a year or two ago such systems are beginning to make their way into
passenger cars, such as the 7 and 5 series BMW's. But again, it's mainly to
make parking and low-speed maneuvering easier and is phased out at pretty
low speeds. Papy uses exactly such a system with their games, from GPL on;
it boosts the lock at low speeds for use in hairpins and pit stalls. They
only allow you to turn it on or off in a config file, not with a slider in
the game menu.
Whatever settings you like to use is fine of course. They're YOUR games,
after all. But you might try to understand better what the effect actually
is before suggesting that a company is derelict in their adherence to
reality by leaving it out.
