Developer MAAN released OpenDLSS-NR, an open-source Vulkan reimplementation of NVIDIA's DLSS 5 Neural Rendering that runs on RTX 40 GPUs and includes a WebGPU implementation for web browsers. The project recreates the original neural network with bit-exact results and includes optimized kernels for Tensor Cores, though it requires users to supply NVIDIA's proprietary model weights separately.
