These are my latest settings.
I have been using driver version 381 and Fanalab 1.53 without any problems so far, a couple of small changes to settings as listed below.
In game setting.
SMOOTHING - 2
Min FFB - 2.5%
Vehicle Set - Ticked
Wheel settings.
SEN - 900 (Had to set to this with the latest version of Fanalab to get the correct wheel rotation. If you are not using Fanalab AUTO will probably still work.)
FF - 100%
DRI - -3
FEI - 80
FOR - 60%
SPR - OFF
DPR - OFF
BLI - 85%
SHO - 100%
BRF - 50
Also a setting change in the Controller json file.
Set to 1 instead of 0
"Steering resistance type":1,
"Steering resistance type#":"0=use damping, 1=use friction",
This setting is not a huge difference but seems that you can feel slides better and when your loosing grip and also easier to save slides. This can be used with the older drivers as well not just the latest drivers. I have found this to be a worth while change.
I have also found that the FFB multiplier in the game settings is very important, if you set it too high the FFB drowns out a lot of fine detail. It's better set it to a low setting to start with and then increase it until you start to loose detail and then come back about .2 to .5. My typical settings range from .6 to .95, this is car dependant, average setting .65 to .8.
The 381 driver seems to make the wheel feel smoother without loosing detail with the settings above.
Hope some of you may find this useful.
