(1) Anyone knows idiot proof guide to F1 developers menu? Especially FF section. Would like to play with it a bit
lol, no. Stuff in there seems only for people with IQ of a whole nation. I usually just fiddle with numbers until the game crashes

(2) What Windows settings do you guys use for G27?
Not in front of my gaming PC at the moment but i didn't change any windows/logitech setup. I dropped the ingame FF to 50, deadzones, speed sensitive FOV, and speed sensitivity to 0. World movement on 100 (=no car movement)
Feels decent to me. I could probably make it better by tweaking the windows settings but i'm not fiddling with them until the FF/controller code is finalized.
