How NVIDIA DLSS upscales games to boost performance

Engadget explains that NVIDIA's DLSS renders a game at a lower resolution, then uses machine learning to upscale it to the display's resolution. Its modes balance image quality against frame rate; more aggressive settings can look blurry. The DLSS name also covers frame generation and ray reconstruction, while DLSS 5 adds an AI visual filter that lowers frame rates rather than boosting them.
