Battlefield is an outlier though - along with a few games that came out at the start of the generation.
Since then I would say that most of the multiplatform comparisons done by Digital Foundry have shown a ~10% resolution improvement of Xbox Series X over that of the PS5. Sometimes this results in additional dips to frame rate but I suspect that developers are okay with 55fps to 60fps on the Series X since it has VRR. Sometimes performance is on par despite the gap in resolution targets.
All in all I would say that Series X has started to perform as expected in comparison to PS5 and I would imagine that this trend is pretty set for the rest of the generation.
