Input lag on Xbox One

I say this respectfully, not hating. I know most people probably don't notice it, but there is definitely some input lag on the standard Xbox One and Xbox One S.  I just want to say that I'm more than willing to sacrifice some visuals so that the game runs at 60fps with no input lag. People will not mind it, most won't notice it, specially when your game is free. Look at fortnite graphics. Look at call of duty, at $60, they still sell every year. Saying all this because, besides obviously not liking input lag, I am also worried that you will not want to support mouse and keyboard on console, and crossplay between PC and consoles because of this issue. Thank you.
