The oldgen versions are plainly in need of an urgent patch. I think the main problem is that some visual settings have not been adjusted in these versions. On PS4, for example, the shadows are lower than on Xbox One (among other sections). Lowering the quality of these and other settings would greatly improve performance. Series S, unlike Series X, does not have several display modes and its performance is somewhat better than in OneX, although it also suffers drops and goes to a lower resolution on average. I was surprised that in Series S I found a much higher number of NPCs than in the rest of the platforms, but perhaps it was due to the precise moment of the recording. As I have mentioned before, I will be aware of the next patches that are published and keep you informed, since I am aware that it is an important game for many of you.
