Although these comparisons are PS3 vs. PS4, I put this here because it's a multiplatform title, and the improvements to X1 will be similar.
As you can see, Rockstar has made good use of the Playstation 4’s power. They have cited use of better reflections and lighting, and smoother textures.
Rockstar Games has shared additional details on what’s coming to Playstation 4, Xbox One, and Windows this fall. There will be new wildlife, such as cats and hammerhead sharks, better foliage, more traffic, and more details on vehicles, including interiors and cockpit view. There will be new jobs, weapons, vehicles, properties, and player customizations.
