Sons Of The Forest is surprisingly detailed, but you don't have much time to take in the sights and the foliage when there's cannibals chasing you through the woods.

I really like the hunter call of the wild. it's not perfect visually, but there have been moments when i just stop to look around and not even care about hunting

Many of those already mentioned are great looking. I would add a personal choice, aesthetically pleasing for my taste: Dyson Sphere Program.

The Witness

Blasphemous. Part 2 just released, btw

I find peace and beauty in the wilderness of DayZ

I would definitely suggest Heaven's Vault, very good, vibrant artwork in that game, and lots of variety.

Both Subnautica games and Tunic.

I played Ratchet and Clank: A Rift Apart recently because it was available free on PS+ and it is the most gorgeous game I have ever played in my life.

The graphical capabilities are astounding, the aesthetic is pleasing, and there is charm out the wazoo. You can't look anywhere without seeing something interesting making use of all that fancy graphic tech. I kept it installed despite 100%ing it just to mess around with the photo mode.

Elden Ring looks beautiful. You just need to get used to fighting a boss 100+ times before killing him ;_;

Horizon series is good. The 2nd game, Forbidden West is so good I used to open the photo mode at random spots and take pictures because I found the scenery beautiful. I would definitely recommend it.

Ghost of Tsushima is also beautiful. However I got bored pretty quickly but others have enjoyed the game so maybe you'll like it.

Also Skyrim with mods (like ENB) can be beautiful as well :p

Genshin Impact, Icarus, Valheim, Stray, Cloudpunk, Growing Up, The Division 2, Cyberpunk 2077, Blockhood, Eve Online, Days Gone, Dredge and the Metro Series. (ꈍᴗꈍ)

Dust: An Elysian Tale. The art in this game is colorful and beautiful. It's one of my favorite games for many reasons.
