A Vulkan reimplementation of NVIDIA's DLSS 5 Neural Rendering network, bit-exact against the original. The same 71-block Swin / ViT network as DLSS-NR build 310.8.0, running FP8 on the tensor cores. The intermediates match too, not just the final image: all 75 block boundaries, byte for byte. ports/browser-webgpu/ is a second, independent implementation: the same bytes in a browser, with no tensor cores and no FP8. You supply the weights, as a model directory in the layout described below. A U-net of shifted-window transformer blocks with a global ViT at the bottom: 71 blocks over six pooling levels, FP8 (E4M3) activations with FP16 accumulation, 141 MiB of weights. It is a generative neural rendering network (NVIDIA's term): it re-renders the frame the engine already drew, generating detail from injected noise and adjusting tone, structure and skin under a style setting. Input and output are the same resolution; it is not…

Topics and intended use
No topics were included in the latest source metadata.
Review the README for scope, installation, examples and limitations. We do not run repository code or certify it.
Evaluate before installing
Review licensing and dependencies, inspect recent commits and unresolved issues, and test in an isolated environment before production use. Stars and forks alone cannot answer these questions.
