DLSS
NVIDIA's deep learning-based super-resolution technology that uses convolutional neural networks to upsample low-resolution frames to higher resolutions. It incorporates temporal information to compensate for motion details, improving both rendering performance and image quality in games.

DLSS Ray Reconstruction achieved near-real-time viewport operation in Blender.
DLSS (Deep Learning Super Sampling) is a set of image enhancement technologies that Nvidia has offered since the RTX 20-series graphics cards; the basic principle is to render the image at low resolution, then use a neural network model to upscale it to the target resolution (such as from 1080p to 4K), while using motion information from adjacent frames to fill in details.
The core idea of DLSS is to use a neural network to infer high-resolution results from low-resolution frames, thereby reducing the GPU rendering load while maintaining image quality.
NVIDIA delegates the DLSS inference process to the Tensor Cores on RTX graphics cards and schedules it through a proprietary driver.
The DLSS super-resolution inference for a single 4K frame must be completed within 1–2 milliseconds.
Without official training weights and Tensor Core-level dedicated acceleration, the open-source project will in all likelihood fall short of the original DLSS in terms of real-world performance.
DLSS's neural network weights are NVIDIA's trade secrets and copyright assets; directly extracting or distributing these weights would expose the project to clear legal risk.
A more realistic compliant path is to use publicly available super-resolution network architectures (such as ESRGAN-derived structures) with self-trained weights, achieving interface-level compatibility with DLSS rather than byte-for-byte reproducing NVIDIA's model.
AI super-sampling technology renders images at a lower resolution and then uses a neural network to upscale them to a higher-resolution output; NVIDIA's DLSS, AMD's FSR, Intel's XeSS, and Apple's MetalFX all belong to this category.
The RTX upsampler is an AI super-resolution technology provided by NVIDIA for RTX graphics cards, based on the DLSS/DLISR approach and leveraging dedicated Tensor Cores to accelerate inference.
