INPUT LAG GAMEPAD ON SERIES X ON GAMES BACKWARDS COMPATIBLE

I’ve been looking for this for a few days now, and I am having the exact same issue. It is NOT a controller issue, it is completely due to the Xbox series X. In my case, I played call of duty Black Ops (1) on my Xbox one , everything was smooth and even played BETTER than on the 360. I recently got the Series X and it made this game nearly unplayable. I know this isn’t a controller issue due to the fact that I am using the same controller for the Xbox one. (It’s a series X controller) the issue specifically that I’m having is with the stick input delay. I move the stick and there’s a noticeable delay when it moves the characters view in game( input). it makes it extremely hard to play FPS games (that rely on looking around with the analog stick) that are reverse compatible (xbox 360 games). Again, no issue on the Xbox one, only the series X. I’ve had to other issues with this on current gen FPS games. Although I do feel the same input delay when I play Overwatch 2. I’m not sure if that is a related issue or just one of the OW2 unique crossplatform setup. I’ve changed look sensitivity for Black Ops, thinking it was that did not change a thing. This is my favorite game and the main reason I got the series C and I’m extremely disappointed I can’t enjoy the game anymore with this issue .

Hi, sorry for the inconveniences
Please report this problem to the Xbox team, you can find the full steps if needed in my previous reply

Don't forget to be as detailed as possible and share your specific setup (controller, screen, Xbox config, etc) in that way is more easy to them to replicate the issue.
Hopefully it will be reviewed and fixed as soon as possible

When I had PS5 backwards compatibility with PS4 was much smoother and faster than series x

Have you updated the controller firmware using the accessories app?

Backwards compatibility with PS4 is essentially trivial as the hardware is nearly identical

Can you take a video demonstrating your lag?
