Xbox One S slow/laggy/dropping FPS

Hi, I have an Xbox One S GoW4 special edition in I have it almost since it launched, recently while playing games, specially Halo Wars 2 and City skylines, it starts laggi t to the point were it is really difficult to keep playing the game properly. It doesn't
matter if I'm online or offline.

When the match starts everything is going well, but as soon as it starts getting some were between a medium sized to a full scale game it just gets to slow, even while playing 1v1 some times, and while playing offline it is annoying but while playing online
it is anoying and unfair because i can't control in real time what's happening while every body else seems to be able to do (that's why I don't know if it's a general problem or is it just my console, and if it's just my console... why?).

While playing City Skylines even when having a small city the games starts lagging, some times crashing after a while.

I mean a know these games might be kind of "heavy" games to proces but the Xbox should be able to run them fine, at least Halo Wars 2 being an exclusive....

Is there anything I can do to fix this??

:)

 

Do You Like The 360 or XboxOne Home Screen Better

360 one I just wish it wasn't so slow and laggy but that's what happens with aging hardware, hopefully they bring more of those looks to xbox one

 

I apologise Microsoft

Again that game also hasn't been shown on a real ps4, only knack has been shown on a real ps4, albeit with severe frame rate dropping and slow down and freezing, knack runs at 30 to 60 fps.
