De langverwachte Alan Wake zal binnenkort toch echt in de winkels gaan verschijnen. Er waren vorig weekend echter wat vraagtekens rondom de resolutie waarop de game afgespeeld zou worden. De geruchten gingen dat de resolutie 520p zou zijn, maar ontwikkelaar Remedy zegt dat Alan Wake een 720p-resolutie heeft. Markus Maki van Remedy had er het volgende over te zeggen;

Modern renderers don't work by rendering everything to a certain final on-screen resolution, but use a combination of techniques and buffers to compose the final detail-rich frames, optimizing to improve the visual experience and game performance. Alan Wake's renderer on the Xbox360 uses about 50 different intermediate render targets in different resolutions, color depths and anti-alias settings for different purposes.

These are used for example for cascaded shadow maps from sun & moon, shadow maps from flashlights, flares and street lights, z-prepass, tiled color buffers, light buffers for deferred rendering, vector blur, screen-space ambient occlusion, auto-exposure, HUD, video buffers, menus and so on.

In the end all are combined to form one 720p image, with all intermediate buffer sizes selected to optimize image quality and GPU performance. All together the render targets take about 80 MB of memory, equivalent in size to over twenty 720p buffers
