I've been playing a ton of Cities Skylines II since its release a week ago. After building a 230k population archipelago I started playing around with the in game cinematic video tools and this is the result.
This is 100% in game footage and effects using the Photo Mode. Recorded using the Microsoft/Xbox Game Bar, only editing was to trim the start and end.
Anti-aliasing? Pop-in on textures and geometry? Shadows? Looked like some z-fighting there too.
There was a nice-looking model train, though.
This has been rendered in real time in a game engine. I find it quite impressive how good it works and how versatile the tooling to create such animations is.
I've got pretty low standards when it comes to graphics. The first game had AA issues too, but generally looked much cleaner and more polished.
