I saw the video from Digital Foundry who are brilliant when it comes to graphics analysis. They found out that the highest PC setting in "clutter" (grass, foliage, ...) is actually lower than the one found on PS5. An extreme high option is missing here.
Video - jump to minute 8:
Is UbiSoft aware of this?
Would love to see a new option on PC since there is no reason, this is missing.
