With the recent announcement that the previously PlayStation 4-only
Horizon Zero Dawn was coming to PC, we didn't get any technical info relating to what sort of port it will be. Well, with the first screenshot of the PC version going up on Steam (
seen here) we know that the game will support ultrawide resolutions and displays.
The 3440×1440 image is confirmed to be from the PC version of the game by Guerilla Games with more details as to what other features are coming to this version expected shortly. With ultrawide support things are boding well for a port that will feature a number of visual upgrades over the PlayStation 4 version of the game.
If we had a wish-list it'd mostly read increased draw distances for foliage in addition to more grass and tree goodness ala the excellent Red Dead Redemption 2 PC port.
