DLSS 3 consists of 3 technologies – DLSS Frame Generation, DLSS Super Resolution, and NVIDIA Reflex.
DLSS Frame Generation uses RTX 40 Series high-speed Optical Flow Accelerator to calculate the motion flow that is used for the AI network, then executes the network on 4th Generation Tensor Cores. Support for previous GPU architectures would require further innovation in optical flow and AI model optimization.
DLSS Super Resolution and NVIDIA Reflex will of course remain supported on prior generation hardware, so a broader set of customers will continue to benefit from new DLSS 3 integrations. We continue to train the AI model for DLSS Super Resolution and will provide updates for all RTX GPUs as our research
