I followed your guide and it's amazing, now I feel a lot more but I have a problem. I don't think it is made by this setup but maybe you met something like this before. When I'm driving more than approximately 50 kph I can't turn car's wheels more than 25-30% even when I turn my DFGT to the maximum. Almost every oversteer ends with a spin and when cars slows down the wheels slowly go to the maximum. I tried to uninstall the logitech drivers but the problem still remains. It doesn't appear in other games. I will be really grateful if someone can give me some advice.
There you are. Posting a question to a forum full of intelligent people and nobody understands how to help you with the simple speed sensitivity setting.
Turn down "speed sensitivity" in the settings and you'll be fine! This setting is for keyboard users.
Edit: YardStick, you already said that. Sorry, I overlooked your post, mate!
