There are tons(or Tonnes if you are Euro) of posts about this topic
going allll the way back to F1 2k. you can google groups ras and search
for controllers and probably find out more than you'll ever want to know.
Basically, if you want to match the 100% linearity of the Papy sims, then
you need to set your sliders in both the logi profiler and the ISI/GTL sims
to 50% Less than 50% slows down the steering some, and more than 50%
begins to make it quicker, more twitchy, more nervous.
Deadzones to zero. Speed Sensitivity to zero. The lower the steering lock
percentage inside the setups, the slower, smoother the steering. But also,
the lower you make the %, the wider your car turns...so sharp corners
become a problem. 15% to 18% should suffice.
