Bad form, I know, replying to one's own post, but I have done a
quick test.

Papyrus NASCAR Racing 2003
Sitting in pits 100fps FF ON 110fps FF OFF
Driving 143fps 141fps

[Odd that, big difference to fps while in pits, no significant
difference while driving, at least on this one track at the same
point for both tests]

ISI rFactor 1.070
Sitting in pits 99-102fps FF ON 100fps FF OFF
Driving 64-65fps 95-106fps

[Pretty *big* difference in fps while driving!]

Summary.

OK, a *very* cursory test, and not one that would stand up to any
rigorous examination. The rFactor test involved one car (rF3) at
one track (The Mother), although I did at least use the same spot
on the track to measure the fps while driving -- halfway between
pit exit and T1.

Both the games were used in "testing" mode, offline and with only
one car on the track. Online lag might make an even bigger (or
smaller) difference to the fps with FF turned on, and the addition
of other cars -- generally an fps hit -- might also increae or
decrease the fps differences. I'll let someone else with more free
time work on that aspect.

I have to say that I *like* FF; it not only adds to the sense of
being there, but I find it improves my feel for the handling of the
car as well. I can no longer recall the original premise: was it
that all wheels suffer a drop in fps in ISI games, or was it that
the old Logi wheels suffer and newer wheels do not?

In any case, I'll stick with using FF in rFactor, even with my
antique wheel. <grin> Anything better than 50fps is smooth enough
for my driving skills anyway.

All the best,
