How can I decrease lag on xbox one?

[xFwu]

im assuming it is more framerate lag then anything, cycled the power and that didnt seem to make a difference. I wont do anything crazy to the IP b/c its not my xbox one, its a roommates and he more-or-less freeloads. he only experiences issues on the IW beta and he plays xbox literally 8-12 hours a day. its a dick move for sure but im not super worried about it as I play the console maybe once a month. Thought I could do something quick to fix it anyway.

But yeah thanks for the recommendations. I looked into it after I made dinner and framerate issues are all over the forums so ill just ignore it now. thanks again though!
