I read quite an interesting post about this on the 3Dfx server
yesterday, supposedly quoting a GPL developer:

As for CPU usage, I have seen a post by Randy Cassidy, one of the
designer of Grand Prix Legends who tested some FF wheel and here's his
quote:

"Of the wheels I've tried, the Force GT (USB) causes by far the
greatest CPU hit. On a PII-400, it takes about 3.5 million CPU cycles
(about 8.75 milliseconds) to issue a simple force command. This is
unconscionable!

By contrast, the Logitech Wingman Formula Force (serial) takes about
50,000 cycles (about 0.12 milliseconds), and the Microsoft Sidewinder
Force Feedback wheel (game port/MIDI) takes about 1.5 million cycles
(about 3.75 milliseconds - still very, very high, but servicable;
drops
to about 1/3rd this amount if the wheel and pedals are stationary, but
what good does that do you?)"

I wonder how much of that is coming from the port and how much is the wheel
itself?

One would imagine that there would be a way to switch _off_ the force
feedback, if required.

The perfect solution to anybody having problems playing with FF
online. ;)

Griffin...

To supplement the ability to turn off force feedback at the controller
level, GPaL will also allow you to turn off force feedback through an
appropriate selection from the Control Set dropdown box in GPaL's Race
Central screen. Take a peek at www.RaceLive.com/GPaL.

Yeah, that thread is on this list too. :)  So yes, he did say that.

I think the uSB is pretty fast, so in the Force Gt case it must be the
wheel or the drivers. Not sure about the MS wheel.

I second that.

I find it much easier to corner in Viper racing now that I can feel my
car get loose. Before, I would often find myself starting to push out
into a guard-rail or be spun around ass-backwards and not know what
happened. The FF lets me progressively feel the over or understeer
start to happen and allows me to take corrective action. There's a
great feeling in Viper Racing of sliding around the switchbacks of
sunset mesa with the wheel letting you know when you have regained
traction...

If someone is scrapping the wall and constantly hitting things,
maybe. However FF will force you to drive smoother. I worked
for me in F1RS. It really does add quite a bit to the experience.

Perhaps there should be a FF only online league for real men (and
ladies).

Im curious about individuals who love FF.   Now, Im not slamming FF <G>
Ive only used it a few times on various games. "not simulations".

My question is this.  If drivers choose to use FF online, wont they be
at a disadvantage?   I would think that having to deal with more
feedback would give the individuals using non-FF wheels an advantage
because they could be smoother, etc.

Although I would imagine that FF would be pretty cool to just run around
with offline.

The disadvantage: CPU cycles going to the routines handling FF
The advantage: Knowing through the wheel what those front wheels are doing
w/o having to look at them.

I've tried Viper Racing both with and without FF and I must say I am faster
WITH FF simply because I know what those wheels are doing BEFORE I see the
results of my course corrections.

Best advice I can give is to try Viper Racing...its a great platform for
showing a good decent start at FF in racing games.

So you're saying that people who haven't invested in FF wheels for lack of
money for example, are sissies? If not, perhaps you should rephrase that ...
