Why does the game downgrade from Xbox X to Xbox One

I understand what you are saying, except the game plays perfectly on my old Xbox one account, perfect picture. But when I switch to my daughters account, then there is this issue.

Is it because it's a 2nd account. It's never been an issue before though

well my first guess would be that because an Xbox one has about a 8th of the power of an Xbox series X, the game does not run in nearly as high resolution

this would definitely come in to play in a scenario of high particle effects like fog

It doesn’t allow me to downgrade on my controller, it’s a series X one which came with the console but it lets me downgrade some of my old ones from Xbox 1.

Coming from the Xbox One S, Forza 7 played perfectly. Got my Xbox One X and now it’s taking 15 seconds to load stock paint jobs. The Subaru legendary BRZ instead of showing up as metallic showed up as primer gray. WTF? This is a horrible downgrade at
the cost of $550. If you are looking to get the One X for this game,

If the games i named can be port on Xbox 360,why Forza Horizon 2 doesn't use Forza 5 game engine or Drivitars,why in Shadow of Mordor' Nemesis system isn't the same on Xbox 360 & One,why all these games looks better and bring new expirences on Xbox one

Maybe because devs have to downgrade for Xbox 360 and upgrade for Xbox one.

Take the Xbox 360 library,downgrade it and you will be able to play all of them on the original Xbox.Where are those famous Xbox 360 "next-gen" games,now?

I think,you just try to find an excuse to keep complaining....

And there is no devs hypocrisy, making two different versions of the same game but there is hypocrisy from someone who played Resident Evil or Minecraft or Another world on his $500 "next-gen" console.
