Deep learning super sampling, or DLSS for short, is a way for computers to make images look better. It works by using a special kind of computer program called a neural network, which tries to learn how to make the image look better by looking at lots of examples.
Imagine you have a drawing that you made, but it looks kind of blurry and pixelated. DLSS is like having a friend who is really good at drawing come and help you. Your friend looks at your drawing and tries to make it look better by adding more details and making the lines smoother.
Now, imagine that your friend has to do this for thousands of drawings. That would take a really long time, right? But with DLSS, a computer can do this much faster because it can work on lots of images at the same time. It's like having a really fast and very smart friend who can help you with all your drawings.
So, DLSS takes a blurry or pixelated image, and uses a special program that uses a neural network to analyze it and make it look better. This is great for video games or movies because it can make them look more realistic and detailed, which makes them more fun to play or watch.
