NVIDIA DLSS (Deep Learning Super Sampling) is a technology developed by NVIDIA that enhances video game graphics. It uses artificial intelligence to upscale lower-resolution images to higher resolutions, allowing games to run smoother and look better without requiring as much processing power. By leveraging deep learning algorithms, DLSS predicts and generates high-quality frames based on previous ones. This means players can enjoy improved performance and visual fidelity, especially in demanding games. DLSS is particularly beneficial for gamers using NVIDIA GeForce RTX graphics cards, as it takes advantage of their advanced capabilities.
