no Sony release on PC has ended up looking worse than its PS5 counterpart.
Which is objectively false.
You mention Horizon: Zero Dawn (original version) and yet that game actually looks better on PC and not by a small margin. Improved AF, draw distance, higher resolution, vegetation interaction.. the port is unquestionably visually superior to the original console version.
God of War: Ragnarok and Horizon: Forbidden West ended up looking worse than the original PS5 release for a reason or another, be it missing effects, VFX, inferior textures, draw distance, worse reflections and this sort of things while, with the exception of slightly better SSR in FW compared to base PS5, not offering a
single visual advantage over the console version that I can recall.
Aside for IQ in Performance Mode when playing on base PS5 obviously, and the higher potential framerate.
Same story for Uncharted 4 and Lost Legacy, slightly less detailed characters, missing effects (some not shown in the video below), worse draw distance:
Not a single advantage aside for a fixed visual glitch on Nadine's hair still present on PS5.
However, Uncharted 4 can at least be tweaked/modded to increase draw distance to extents superior to PS5.
Insomniac games are all better on PC, with brand new RT settings, increased draw distance, more populated worlds and things of this nature, making them all noticeably more advanced and better looking than console versions.
Not sure if PC version has been updated, but Death Stranding also received some new/revamped graphical features when Director's Cut launched on PS5.
Obviously, this is all result of questionable porting efforts and has nothing to do with hardware.
