John, this is an excellent article! You've described beautifully many
of the factors that have made GPL seem inaccessible to so many people,
and also the immensely rewarding experience that GPL gives if you've got
the hardware to run it well and have the perseverance to get over the
other hurdles.
Force Feedback does indeed make an amazing difference to the experience
that GPL provides. After I'd used a FF wheel for a few weeks, I tried
going back to a passive wheel, and there was just no comparison at all.
I could barely drive with the passive wheel! A good FF wheel gives so
much more information about what the car is doing that once I got used
to it, it's hard to imagine how I drove without one.
I've tried the MSFF wheel, the Act Labs Force RS, and the Logitech
Wingman Formula Force. Of the three, the Logitech is far and away my
favorite.
I felt that the MS wheel has too much internal friction, and its
software also induces artificial damping that makes it very difficult to
make the kind of rapid, precise corrections that GPL demands. Also, the
MS wheel uses an optical sensor instead of a potentiometer, and, while
this is a good idea, unfortunately it lacks precision because the small
slots in the sensor disk are too large and too far apart.
The Act Labs has potential, but in the one I tried, the toothed belts
were much too tight, causing too much internal friction. This
completely dampened all the subtle feedback that GPL gives. The pedals
also had a lot of friction.
The Logitech isn't perfect; the brake pedal is awful, and its wheel also
has more internal friction than I'd like, due to its use of nylon
bushings instead of ball bearings. But I use CH Pedals with it and
these are very precise. Also, by carefully adjusting the force and
damping in the Logitech software and in GPL's ini file, I have it so
that the wheel moves quite freely and transmits all those wonderful,
subtle forces that happen when the car gets light, loads up, the front
end washes out, or the tail starts to come around. It's fantastic!
There are more details about Force Feedback wheels on my GPL pages:

Go to Help, then Controls, then Force Feedback.
Also, if you haven't tried racing against other people in GPL yet,
you're in for a treat. You can race via the Internet any time you want
on VROC at http://vroc.net Peak times are evenings (North American
time) and weekends. There's a club for people who are just getting into
online GPL racing called the VROC Formula 2 Club. Details are at the
VROC site.
I hope to see you online sometime soon! And thanks for the great
article, John. I'm delighted you've discovered GPL!
