Metal Gear Solid 5: Ground Zeroes "looks slightly better on the PS4 compared to the Xbox One", according to Game Informer - a feeling reportedly shared by director Hideo Kojima.

Discussing the game's visuals following a hands-on playtest in its latest issue, Game Informer states that "Kojima Productions' hard work under the hood pays off in the graphics department," noting Fox Engine's impressive lighting and the sight of "watchtowers [crumbling] to hundreds of pieces with an RPG shot".

However, it later adds that "Kojima notes that MGS V looks slightly better on the PS4 compared to the Xbox One, something we also noted before he mentioned it."

It isn't clear from the article how the two versions differ from one another, or whether one runs at a lower native resolution than the other.

A Konami representative told VideoGamer.com that they were unable to confirm the native resolution and frame rates of the two versions when contacted about any potential differences last week.

The revelation will come as a further blow to Microsoft which has already seen major titles like Tomb Raider: Definitive Edition, Call of Duty: Ghosts and Battlefield 4 perform worse on Xbox One than PS4.

Metal Gear Solid 5: Ground Zeroes launches on Xbox One, PlayStation 4, Xbox 360 and PS3 on March 21, with MGS5: The Phantom Pain following at a later date.
