Nvidia’s DLSS 5 runs in a web browser through a WebGPU port
A modder has the neural rendering feature working in a web page, including on macOS, without an RTX card.
A modder known as MAAN has got Nvidia’s DLSS 5 running inside a web browser through a WebGPU implementation, with an interactive demo that also works on macOS.
DLSS 5 is Nvidia’s neural rendering feature, which uses AI to improve graphical quality. Nvidia launched it earlier this month for NBA 2K27, the first game with official support, and it is officially limited to RTX 50-series cards, aside from GeForce NOW.
The demo is hosted on Cloudflare Workers and ships with default scenes, starting with "Cowboy Gramps", plus adjustable settings and a comparison view. MAAN describes it as DLSS 5's neural network reimplemented with WebGPU compute shaders; the weights are around 147MB and the JavaScript runtime around 1MB compressed. The weights were extracted from a leaked DLSS 5 library file.
In a test on an RTX 40-series desktop, the 3D viewer rotated smoothly, but each DLSS 5 render took a second or two and live mode was slow. The demo page accepts common 3D formats by file or drag-and-drop, and MAAN plans to publish the source code on GitHub this weekend. Nvidia has said official RTX 40-series support is coming.
