But why only when the player is moving? Surely the NPCs are also moving all the time, so just moving the player and maybe nudging the party members (so like 4 new characters moving?) shouldn’t drop frames by ~30%. Something seems off there.
I hope they figure it out and patch it, because it would really impact the experience on lower end hardware, like the Steam Deck (i.e. stable 30 FPS vs stutters in the late game).
