Battlezone

The 1.02 patch released on October 27 adds increased supersampling resolution, improved dynamic lighting in the Cobra cockpit, and increased reflective lighting resolution. It's unclear at this point how these improvements are applied on 1080p and 4K displays.

Call of Duty: Modern Warfare Remastered

PS4 Pro with a 4K display:

Improved textures and a "dynamic" 4K resolution while maintaining the standard 60 FPS frame rate.

Deus Ex: Mankind Divided

PS4 Pro with a 4K display:

4K resolution and graphical improvements.

The Elder Scrolls Online

PS4 Pro with a 4K display:

Increased graphical fidelity running in native 4K resolution.

PS4 Pro with a 1080p display:

Increased graphical fidelity.

Fallout 4

PS4 Pro with a 4K display:

Bethesda said it expects the game to "take advantage of the PS4 Pro in 4K along with enhanced lighting and graphics features," but didn't provide any further specifics.

Horizon: Zero Dawn

PS4 Pro with a 1080p display:

Improved shadow maps, extra detail, and enhanced colors. It'll feature higher quality anisotropic filtering, which means upgraded texture sampling, resulting in more detailed environments. Additionally, supersampling will render Horizon's resolution at a resolution "close to 4K" and then shrink it down to 1080p, Guerilla Games says.

PS4 Pro with a 4K display:

A 2160p checkerboard, which Guerilla Games says is a technique that "looks incredible" on a 4K display. It's supposed to add noticeable detail to aspects, such as "stitching on Aloy’s outfit, individual leaves and branches swaying in the wind, kilometers away in the distance, and more detail in all the machines and NPCs in the world."

Killing Floor 2

PS4 Pro with a 4K display:

1800p checkboard rendering on 4K TV (3200x1800) optimized for 4K TVs.

PS4 Pro with a 1080p display:

Increased framerate and supersampling, as well as increased texture resolutions (which may also be present at 4K).

Middle-earth: Shadow of Mordor

PS4 Pro with a 1080p display:

Super sampling anti-aliasing.

NBA 2K17

PS4 Pro with a 4K display:

Native 4K resolution running at 60 FPS with HDR support.

PS4 Pro with a 1080p display:

2K confirmed to GameSpot that it will still render a 4K resolution even on a 1080p display. The company said this should result in "much better anti-aliasing" with HDR support.

Paragon

PS4 Pro with a 1080p display:

Enhanced visual effects, procedural ground cover, higher scene complexity, greater texture fidelity, and dynamic reflections.

Thumper

PS4 Pro with a 4K display:

4K resolution with no upscaling.

PlayStation VR:

Improved rendering quality at the same 90 FPS as the regular PS4.

Titanfall 2

Producer Drew McCoy explained in an interview that the PS4 Pro version of Titanfall 2 will not run in native 4K. However, the console's extra power should help the game stick closer to its 60FPS target. Read the full interview here to learn more.

The Witness

PS4 Pro with a 4K display:

1440p resolution or possibly higher upscaled to 4K with a consistent 60 FPS. Text, menus, and other UI will be set at native 4K.

PS4 Pro with a 1080p display:

1080p resolution instead of 900p and increased antialiasing quality from 2x to 4x MSAA, while keeping a solid 60 FPS.

Destiny

A PS4 Pro patch is not in the cards right now, but could happen later, Bungie said.

The Witcher 3: Wild Hunt

"Since we want to fully focus on Cyberpunk 2077 and Gwent, and converting The Witcher 3: Wild Hunt from a full HD game into a 4K one would be too much of a time and resource-consuming process, we decided not to release an edition of Wild Hunt supporting the new features of PlayStation Pro," CD Projekt Red said.
