They already do it in more evident texture/gloosy ground , whether it's a bug or not.They always mentioned differences of this kind, usually accompanied by a "This is likely a bug and we've contacted the devs about it".
This time they didn't, and I'm not sure if you played the game but this ain't a minor thing.. those buildings/distant views are right in your face for the entire game.. except for rare angles like the one they chose for their comparison.
There is perfectly the possibility that whoever made the comparison has not played both versions at the same time in those areas. As obvious as it may be putting one catch on top of another is not the same as while playing, at least not as much as the ground situation.
Wanting to look for intentionality, when he himself points out better reflections in the police station when he could very well have not pointed out...
That said, the fact that the divergences clearly occur in the same environment where XSX has an advantage of at least 10fps and the same "bug" also occurs while in the rest of the areas it does not is illuminating.
Then, it is also curious that LOW on PC does not show that ground appearance (which gives more support to the possibility of a bug). It would be interesting to check if in LOW the detail of distant buildings compares with the appearance in XSX or not.
That advantage of more than 10fps in favor of XSX in that specific area must come from somewhere...
