I respectfully have to disagree with the bolded. I played these games back to back (H:ZD immediately followed by GoW), 100%ing both of them on the same PS4 Pro on the same TV. While GoW definitely has better looking/more detailed character models/animations, it seems to have much lower resolution reflections/lighting/special effects. As I'm playing it, I can see the dithering (or whatever it's called on modern machines) in all of the energy blasts, fire, reflections on the water, etc. All energy and particle effects appeared much smoother in H:ZD to my eyes. Also, the LOD/draw distance was more impressive in H:ZD. GoW seems much quicker to sub in 2D assets, relying on flatter skyboxes more readily, as opposed to H:ZD's willingness to render things in 3D much further out. At least that's how it all looked to me.
Eh, nah. I stand by that original statement from 2 years ago. God of War is a more technically sound game, even if Horizon has its advantages.
