Is This FIFA 15 or the Hardware?

I have had this 'stuttering' effect for months on FIFA 15 but i'm not sure it was there when i first purchased the game... It is like a stuttering/Choppy/FrameDrop... I have tried everything, hard reset after hard reset, reinstalled the game, factory reset
the console, factory reset my tv, enabled 'Game Mode', used 2 different HDMI cables... Is it Hardware, is it a recent patch for the game itself?... Also the gameplay now is nothing like it was when the game was first released, Online or Offline, turning players
is like turning trucks! players can't seem to sprint anymore... Always lose the ball.. That might be a seperate problem to the above stuttering, brand new X1 controller connected with USB cable and still it does not feel as fluent as it once was, or atleast
how i remember it being... Is anyone else having this? Is there a fix? Is it my hardware or is it just EA and the release of a bad patch? I have attached a link to a video with some clips showing this 'Stuttering' in replays, this has become really
annoying! I just want to know if its my hardware or the game and if anyone else has it, here is some clips:

XB1 console/fifa bundle

Purchased this xbox one bundle with a fifa 15 download code , looking to sell the console , what happens with fifa 15 ?

Can the new buyer play fifa 15 or is it tied to my gamertag ??

 

Fifa 14 or Fifa 15

Is fifa 15 worth getting or should I get Fifa 14 ?

 

Are you having these problems in multiplayer games on FIFA 15 or solo games too? If you are having these problems on multiplayer then it is probably just a bad connection between you and the other people in your game.

 

I wish that was the problem, i factory reset my router and had UPNP enabled & then disabled as that is known to cause issues with FIFA 15 but no it also happens offline even with my internet unplugged leaving just the power cable and the HDMI cable in the
X1 which is another reason i am thinking it is hardware related, update or patch related? I have also tried another Live Account and same results, i have 'Hard Reset' by holding the power button for around 10 seconds untill the system shuts off and then waiting
20 seconds before powering back on, i have also tried this and removed the power brick from both the X1 and the wall outlet they are the only ways i know of to perform a 'Hard Reset'...
