'''Deep learning super sampling''' ('''DLSS''') is a family of [[Real-time computing|real-time]] [[deep learning]] image enhancement and [[Image scaling|upscaling]] technologies developed by [[Nvidia]] that are available in a number of [[video game]]s. The goal of these technologies is to allow the majority of the [[graphics pipeline]] to run at a lower [[Display resolution|resolution]] for increased performance, and then infer a higher resolution image from this that approximates the same level of detail as if the image had been rendered at this higher resolution. This allows for higher graphical settings and/or [[frame rates]] for a given output resolution, depending on user preference.<ref name=":2">{{cite web|url=https://www.digitaltrends.com/computing/everything-you-need-to-know-about-nvidias-rtx-dlss-technology/|title=Nvidia RTX DLSS: Everything you need to know |publisher=[[Digital Trends]]|date=2020-02-14|access-date=2020-04-05|quote=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.}}</ref>

All generations of DLSS are available on all [[Nvidia RTX|RTX]]-branded cards from Nvidia in supported titles. However, the frame[[Frame generationGeneration]] feature is only supported on [[GeForce 40 series|40 series]] GPUs or newer and multi[[Multi-frameFrame generationGeneration]] is only available on [[GeForce 50 series|50 series]] GPUs.<ref name=":3">{{Cite web |title=Introducing NVIDIA DLSS 3 |url=https://www.nvidia.com/en-us/geforce/news/dlss3-ai-powered-neural-graphics-innovations/ |access-date=2022-09-20 |website=NVIDIA |language=en-us}}</ref><ref name=":6">{{Cite web |title=NVIDIA DLSS 4 Introduces Multi Frame Generation & Enhancements For All DLSS Technologies |url=https://www.nvidia.com/en-us/geforce/news/dlss4-multi-frame-generation-ai-innovations/ |access-date=2025-01-14 |website=NVIDIA |language=en-us}}</ref> Nvidia has also introduced '''Deep learning dynamic super resolution''' ('''DLDSR'''), a related and opposite technology where the graphics are rendered at a higher resolution, then downsampled to the native display resolution using an [[artificial intelligence]]-assisted downsampling algorithm to achieve higher image quality than rendering at native resolution.<ref>{{cite web |last1=Archer |first1=James |title=Nvidia DLDSR tested: better visuals and better performance than DSR |url=https://www.rockpapershotgun.com/nvidia-dldsr-tested-better-visuals-and-better-performance-than-dsr |website=Rock Paper Shotgun |date=17 January 2022 |access-date=23 February 2022 |ref=dldsr}}</ref>
