Frame Rate on Xbox Series X

I’m liking what I see, so keep up the good work. My first impression of the game is that it has frame rate drops on Xbox Series X when playing in performance mode and its very noticeable at this early stage that’s my only issue.

How do you switch modes? Mine is set to quality, but is greyed out and won’t let me change it. I always play in performance where possible.

I don’t have that issue on Xbox Series X, I can switch between Quality and Performance, I have a TV that can handle 4k at 120Hz, maybe its a display thing.
