Given that Sony has been touting Horizon: Zero Dawn as a example of why 4K and HDR matters, you'd expect the game's performance to be pretty solid. And good news: it is.
As you'd expect, Digital Foundry has been putting Horizon through its paces over the past week. And much like I discovered during my time with the game, it's astonishingly well-optimised, even without the zero-day performance patch that's due out soon for PS4 Pro users.
What's interesting is how consistent the performance between the base PS4 and PS4 Pro is. Both maintain a fairly steady locked 30fps, with minimal frame rate drops during major firefights. Both versions of the game also don't suffer from the frame pacing issues that still plague Final Fantasy 15, which is equally important to a smooth experience.
Something to remember: Horizon is built on the same engine that will be used for Kojima's Death Stranding. Think about how good Horizon looks and holds up, and now imagine how hard Kojima's team will push that engine in a year or two.
