Ghost Recon: Wildlands @ 12K (11520x6480)
I've been playing a bit of Wildlands recently and although the game itself is decidedly average in my opinion, the environments are outstanding. Using Nvidia's Ansel to pause the game and render ultra high resolution screenshots from any angle is great fun, it leads to some breathtaking shots like this:
I really hope more games support Ansel in the future. It blows me away being able to zoom in on parts of the screenshot and see it in fine detail with no artifacts.

I'll post more of these if this post is popular :)
