Guerrilla Games has released a new blog post today regarding Killzone: Shadow Fall, explaining the game’s native 1080p resolution. This was following new information that the game ran at a 1080×960 frame buffer in order to hit 60 FPS.
But this isn’t quite the case. Producer Poria Torkan confirmed that the game runs at 1080p resolution/60 FPS in both single-player and multiplayer, but explained its “temporal reprojection” technique which allowed it to create a full HD image by combining lower resolution frames.
“If native means that every part of the pipeline is 1080p then this technique is not native. Games often employ different resolutions in different parts of their rendering pipeline. Most games render particles and ambient occlusion at a lower resolution, while some games even do all lighting at a lower resolution.
“This is generally still called native 1080p. The technique used in Killzone: Shadow Fall goes further and reconstructs half of the pixels from past frames.”
Torkan said that the developer would “do our best” to communicate its development techniques more clearly in the future, although right now, trying to explain it using the usual terminology is difficult.
