What is NVIDIA DLSS and how does it work?

NVIDIA's Deep Learning Super Sampling (DLSS) is a sophisticated upscaling technology designed to improve gaming performance and visual fidelity. By leveraging artificial intelligence and dedicated Tensor Cores found in NVIDIA's RTX graphics cards, DLSS renders games at a lower resolution before using a neural network to upscale the image to the target resolution. This process significantly reduces the computational load on the GPU, allowing for higher frame rates without sacrificing image quality. The technology has evolved through several iterations, including DLSS 2.0, which introduced better temporal stability, and DLSS 3, which features Frame Generation to create entirely new frames between existing ones. As a cornerstone of modern PC gaming, DLSS has become essential for running demanding titles with ray tracing enabled. It represents a shift in graphics rendering, moving from traditional brute-force methods to intelligent, AI-driven solutions that optimize performance for gamers.
