Re: Sensitivity of Xbox Controller
@nuebelmyes, this should be possible, but I'd guess you have to do it in the windows settings (not in-game). you should find your controller in the list of devices (maybe it is called "device manager"? but I'm not sure how it is named in English since my main language is German). normally, there should be an option to manually adjust the configuration of your controller (incl. sensitivity).
EDIT: doing a quick google search I found this page. I hope this solves your issue: How to Calibrate Your Gaming Controller in Windows 10 (howtogeek.com)
hope that helps. good luck!
