So recently I uploaded a Video on my channel and Od1n uploaded it on his XIMGameplay channel and I've been getting great feedback for my settings which I posted in the video description. My config is very simple and basic but it seems to work for a lot of people so I thought I'd share it here as well.
In-game settings

Some Xbox players are complaining about stick drift in MW and one of the developers tweeted this:
"So we have a fix in our next big update which should fix this for most Xbox controllers. For MW we put effort into reducing the dead zone for the analog sticks on Xbox but we went a bit too far."
