Metal Gear Solid V: The Phantom Pain is currently one of the free PS Plus games of the month, and if you haven't tried it out yet, there's now another reason to jump in: Konami has finally released a patch that enhances the game on PS4 Pro.

The patch was announced on Monday on Twitter, and then it launched a day later. It's a relatively modest update, but it still makes an already good-looking game even better. While you won't see vastly overhauled textures, the game does run at a solid 2560x1440 resolution.
