How to run Halo Infinite at its best on Xbox Series X

So as I played Halo Infinite yesterday I noticed that the quality was “meh” I had it on 4k 60 fps, so the frame rates slowed sometimes during immersive cutscenes like in Training mode. What do I do to increase overall gameplay quality. Without switching to pc

I got low-frame animations occasionally at 4K 60Hz on my own Series X too, and I see it in other places. I think it’s just a bug.

I noticed this as well playing on 120hz, I do not believe it’s frame dips but rather low frame animations if that makes sense. Similar to how camera used to be 30fps in Halo CEA. I believe this can be fixed via update.
