Nvidia's Deep Learning Super Sampling (DLSS) was introduced in 2018 with the GeForce RTX 20-series graphics cards and has evolved into its fourth iteration, becoming a standard expectation for modern PC games. DLSS enhances gameplay by upscaling lower-resolution images, improving frame rates, and enabling advanced graphical effects without sacrificing performance. The latest version, DLSS 4, debuted with the GeForce RTX 50-series in 2025 and features a new transformer model to enhance image quality. DLSS includes Frame Generation, which creates additional frames to improve gameplay fluidity, and Multi-Frame Generation, which can produce up to three additional frames per real frame. DLSS significantly reduces the performance impact of ray tracing, allowing gamers to enjoy high-quality graphics without compromising frame rates. Over 500 games and applications currently support DLSS technology.
