You have me beat on the hours, I only have 173h, though the last 30 or so in 4K with a large image. I believe I have a pretty good grasp on how the game looks as well. Maybe I'll take some screenshots later.
There isn't much far away detail there. Not in the way I'm talking about. You even put an indoor photo in there... The photo what I first quoted is what I'm talking about, a scenery that actually stretches far and has many unique pieces, and it looks terrible. The places with actually long draw distance and where Uncharted looks good are places where you only have simple backgrounds with mountains etc. In all these the scene complexity is quite low. And BTW. I'm not comparing what looks best as a whole, just about the draw distance and the detail level in far distance objects. Indoors and most others close scenery places, Witcher 3 can't touch Uncharted 4. I do admit though. I wasn't blown away, when I played Uncharted 4, to me it didn't really stand out from some other PS4 games I expect small scenes to look nice. Whereas Witcher 3 still on occasion provides truly spectacular views, usually with very high geometry scenes and nice atmospheric lighting, and yeah the 4k definitely helps with the details.
The photo that I quoted and zoomed in doesn't even only contain far away objects. The houses on the left are actually quite close. Maybe around 100m or less from the player. There are many scenes that look really bad in Uncharted, but yeah it's mostly in places where you are not supposed to look like I said in my first post and BTW. I don't need to zoom in on anything. My screen is so close that these just pop in immediately and I think this makes a big difference here, you guys just don't pay attention to the places they don't want you to look.
The problem I have with Uncharted is the inconsistency. It can look from very good to crap, witcher 3 looks consistent, buildings far away (far, not 100m away) actually appears like the same buildings far away instead of houses using PS2 assets. Load up that chapter 3 salvage boat mission and look around from the deck of the ship. The landscape around the river looks atrocious. There are many places in Uncharted 4 where the actual play area 3d world looks amazing, but they don't have anything left for the 3d backdrops. edit: Infamous Second Son looks a lot better in this regard. The scenes look consistent and far away details still keep their details better.
