How to fix Xbox Series S' input lag?

i know my placement isn't ideal for the best airflow hehe

Please help, i have this issue with the input lag on my new XBOX Series S. Coming from a PS5, I can definitely feel the difference in input lag, especially on multiplayer games like Fortnite.

here's what I've initially done:
- Update controllers
- Update the console itself
- I've used both wired and wireless connections and they both seem to have the same input lag still
- my TV is 4K and the output is set to 4K if it helps.
- I also use the PowerA battery kit for both of my controllers if it matters

For those who are on Xbox din, please help ya fellow!
