Sony Sued Over Killzone 1080p Claims
Sony is being sued in the state of California over its claims that PS4 exclusive KIllzone: Shadow Fall runs in a 1080p resolution. According to Polygon, a man named Douglas Ladore filed the lawsuit in Northern California. He claimed the following: Sony advertised Killzone: Shadow Fall as running in 1080p, but instead, in multiplayer, it “used a shortcut that was supposed to provide ‘subjectively similar’ results.”
Back in March, 2014 Eurogamer’s Digital Foundry reported that the game’s multiplayer only ran at 960X1080 at around 50 frames, not the 1920X1080p and 60 frames that Sony claimed.
Digital Foundry wrote the following at the time:
“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 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.”
In a blog post, the game’s producer, Poria Torkan retorted, explaining that Shadow Fall uses some tricks to reach the full 1080p resolution.
“In both SP and MP, Killzone Shadow Fall outputs a full, unscaled 1080p image at up to 60fps. Native is often used to indicate images that are not scaled; it is native by that definition.In multiplayer mode, however, we use a technique called ‘temporal reprojection’, which combines pixels and motion vectors from multiple lower-resolution frames to reconstruct a full 1080p image. 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.”
Ladore did not find this explanation satisfactory enough, and is suing Sony Computer Entertainment for 5 million dollars for false advertisement.
