Earlier this evening, it was reported on NeoGaf that upcoming Microsoft Xbox 360 exclusive, Alan Wake, was only running at the resolution of 547p -- which will be sub-HD levels. Well, to counter these claims, Remedy has claified the situation with an official statement on the Alan Wake forums.
Community Manager stated: "The game is 720p. Those screenshots are based off footage captured at 960x540 like cocorenut pointed out, of course there will be some downsampling involved.
As has said before Videogameszone and Gamepro both released footage without approval and due to the fact that we don't know how many compressions their videos went through or what process they took it's best not to use those videos as sources."
As of now, the statement from Remedy should be the one to go off. Alan Wake will release on the Xbox 360 in a month and will be one of the biggest releases the system in 2010.
