DLSS

深度學習超級採樣（Deep Learning Super Sampling，DLSS）是Nvidia開發的一種圖像縮放技術，可實時用於視頻遊戲中，這種技術利用深度學習將較低解析度的圖像縮放為更高解析度的圖像，以便在更高解析度的計算機顯示器上顯示^[1]。

歷史

Nvidia在2018年9月推出NVIDIA GeForce 20系列 GPU時，將DLSS作為賣點進行宣傳^[2]。當時，DLSS的效果僅限於少數幾款視頻遊戲（如《戰地5》和《戰慄深隧：流亡》） ^[3] ^[4]。 2020年4月，Nvidia推出DLSS 2.0，該版本的DLSS適用於《控制》和《德軍總部：新血脈》等遊戲^[2] ^[5]。

DLSS 3.0於2022年10月發布。DLSS 3.5版本於2023年8月22日發布，《心靈殺手2》、《賽博朋克2077》等將成為應用DLSS 3.5技術的首批遊戲。^[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.

In Metro Exodus, the FPS jump was barely there and certainly not worth the bizarre hit to image quality.
