Despite claims from Sony suggesting otherwise, the multiplayer mode in Killzone: Shadow Fall does not run natively at 1080p and 60 frames per second.
In a new Digital Foundry report exploring the prospect of allowing games to run at 60 frames per second at a resolution of 720p rather than 30 frames per second at 1080p, Shadow Fall's resolution and framerate were examined. The single-player does indeed run at full 1080p (albeit with an unlocked framerate and a recently added option to lock it at 30 FPS), but multiplayer does not. Instead, it uses a framebuffer of 960x1080 -- as opposed to the standard 1080p resolution of 1920x1080 -- that allows it to average about 50 FPS.
"Shadow Fall uses a horizontal interlace, with every other column of pixels generated using a temporal upscale - in effect, information from previously rendered frames is used to plug the gaps," the report explains. "The fact that few have actually noticed that any upscale at all is in place speaks to its quality, and we can almost certainly assume that this effect is not cheap from a computational perspective. However, at the same time it also confirms that a massive reduction in fill-rate isn't a guaranteed dead cert for hitting 60fps."
Sony has claimed in the past that the competitive multiplayer and single-player both run at 1080p and 60 frames per second. However, developer Guerrilla Games itself has made it clear the framerate is not locked at 60 in either mode, as it instead uses techniques that it claims make Shadow Fall look "a lot more detailed and vibrant than a lot of the other games we are in direct competition with."
Whatever the particulars may be, Shadow Fall's visuals were among the things praised in IGN's review of the PS4 launch game last year. PS4 owners who haven't been able to try it out for themselves will soon be able to download it and check out its multiplayer, which will be made available for free for the next week.
