For AF/DD owners, try the Smoother file, set engine_vibration 0.0001, set engine_vibration_while_driving 0.0001, in-game set Volume 70, Tone 50, FX 25, in SimCommander Reset To Defaults, Game Force Feedback Smoothing 48.24%, AccuForce Friction 5.49%. After that, there's still some heavy rattling/vibration from road surface(?) that I haven't been able to tune out. I tried FX 0 and bump_scale/scrub_scale 0.0001 but those didn't seem to work. Hugo, could you compare against Jack Spade's ffb_custom_settings - stan lo comp DD SopDiff.txt file (attached) and see what the difference is because that file doesn't exhibit that rattling/vibration. Thanks!
