Xbox One X acts strangely

What I'm about to talk about is a problem I've been living with for almost a year now and many times I've tried to solve it without success; I've also discussed it in the past through a post and I'd like to re-propose my situation at the moment with another
post on this forum.
On November 7, 2017 I bought, like many others, an xbox one x giving back, to get a discount, my xbox one.
The sacrifice was not futile at all, the graphics surprised me from the very first moment on games like Assassin's Creed Origins and the framerate was smooth and fast on many games.
Through the console I then continued for a year or more to enjoy these games to the fullest of their possibilities, using a 4k Ultra HD TV with HDR; the problem arose during the release of the video game Jump Force, being a good fan of anime and manga
as Dragon Ball, One Piece and Jojo's Bizzare Adventure I bought it without thinking too much.
Time 1 hour and a little more and I immediately realized the terrible performance that the game showed, the graphics seemed great but the framerate was horrible, I could not make simple movements and enjoy the game because of it.
The performance offered by the game did not resonate with what I had managed to define in videos on youtube dedicated to the gameplay of it on an Xbox One X, in those videos everything seemed very fluid and comfortable to play, while from my perspective
the situation was completely different.
One X had never given me much trouble so far so I thought it was just a temporary problem and I calmly waited for a possible update.
Time passed and no updates solved the problem; Undecided on what to do in this situation I asked a question on this forum and despite the many help I was given by admin and player just like me (which I want to thank) I could not solve the problem.
I was offered to reinstall the game, to free up space, to change the HDMI cable, to check my connection to the servers and also to try with a Factory Reset, but none of this had any effect.
Not having other ideas decided to consult with a guy who works in a Game Stop not too far from my house, it advised me at the last minute to send the system to make a check in the German company.
I did exactly that, but the console itself came back to me after 1 month without any trick done and no problem found.
Time passed and I began to notice other problems generated by other games: during the beta of the video game "Anthem" I noticed how the framerate was horrible and how I could barely move; many games generated continuous crashes and others like "Sekiro:
Shadows die twice" had drops in framerate constant though not too invasive.
At this point I decided to make a change of the console, I contacted the customer service and I was delivered in a short time a replacement of the console.
The numerous crashes seemed to end and the framerate of some games seemed to finally stabilize, but not Jump Force.
The point of this long speech is one, recently a friend of mine who owns an Xbox One S bought the game and tried it with me, I realized that on his Xbox One S the game was very fluid while on my Xbox One X, which should be more powerful, had a framerate
really low and invasive.
So I find myself at this point without clues as to what to do, I have tried many things to solve the problem but none has helped, this game seems almost hostile to me in a way.
I'm not sure if anyone has found themselves in the same situation as me but I still hope for someone's help.
Thanks in advance
