深度学习超级采样(Deep Learning Super Sampling,DLSS)是Nvidia开发的一种图像缩放技术,可实时用于视频游戏中,这种技术利用深度学习将较低解析度的图像缩放为更高解析度的图像,以便在更高解析度的计算机显示器上显示[1]。
Nvidia在2018年9月推出NVIDIA GeForce 20系列GPU时,将DLSS作为卖点进行宣传[2]。当时,DLSS的效果仅限于少数几款视频游戏(如《战地5》和《战栗深隧:流亡》) [3] [4]。 2020年4月,Nvidia推出DLSS 2.0,该版本的DLSS适用于《控制》和《德军总部:新血脉》等游戏[2] [5]。
DLSS 3.0于2022年10月发布。DLSS 3.5版本于2023年8月22日发布,《心灵杀手2》、《赛博朋克2077》等将成为应用DLSS 3.5技术的首批游戏。[6][7][8]

Deep learning super sampling uses artificial intelligence and machine learning to produce an image that looks like a higher-resolution image, without the rendering overhead. Nvidia’s algorithm learns from tens of thousands of rendered sequences of images that were created using a supercomputer. That trains the algorithm to be able to produce similarly beautiful images, but without requiring the graphics card to work as hard to do it.
AMD Thinks NVIDIA DLSS is not Good Enough; Calls TAA & SMAA Better Alternatives. techquila.co.in. 2019-02-15 [2020-04-06]. (原始内容存档于2019-02-15). Recently, two big titles received NVIDIA DLSS support, namely Metro Exodus and Battlefield V. Both these games come with NVIDIA’s DXR (DirectX Raytracing) implentation that at the moment is only supported by the GeForce RTX cards. DLSS makes these games playable at higher resolutions with much better frame rates, although there is a notable decrease in image sharpness. Now, AMD has taken a jab at DLSS, saying that traditional AA methods like SMAA and TAA “offer superior combinations of image quality and performance.”
Nvidia Very Quietly Made DLSS A Hell Of A Lot Better. Kotaku. 2020-02-22 [2020-04-06]. (原始内容存档于2020-09-29). The benefit for most people is that, generally, DLSS comes with a sizeable FPS improvement. How much varies from game to game. In Metro Exodus, the FPS jump was barely there and certainly not worth the bizarre hit to image quality.
