I've been experiencing this lag and slowdown on Xbox Series X.

It does this on performance mode and fidelity mode. I've uninstalled the game and its still doing it i even made a new save and it was running smooth at first but it went bad quickly once i got to Arlathan Forest. Can Bioware please put out a patch or something also i'm playing on a digital version of the game i got via EA Creator program not physical plus my other games are running smooth as usual. 

Its like the game isn't fully loading in like exploring the lighthouse and cutscenes are fine its just the gameplay and going to the other regions.
