OpenDLSS NR
An open-source Vulkan reimplementation of the DLSS 5 neural rendering network, released under the MIT license. It supports native execution on RTX 40-series GPUs and cross-platform execution in web browsers via WebGPU.
Timeline (last 90 days)
Developer MAAN rewrote DLSS 5's neural rendering network in Vulkan and open-sourced it under the project name OpenDLSS NR, using the MIT license.
OpenDLSS NR's neural network contains 71 blocks, uses FP8 activations, and has total weights of approximately 141 MB.
OpenDLSS NR achieves bit-exact intermediate output consistency with the original at 75 block boundaries.
On the RTX 4070 SUPER, OpenDLSS NR takes 7.8 milliseconds per frame at 1080P, 12.6 milliseconds at 2K, and 29.3 milliseconds at 4K.
The above performance figures are from the developer's own testing and are not independent third-party benchmarks.
OpenDLSS NR provides a browser version that runs using WebGPU and does not depend on TensorRT.
The browser version is approximately 27 times slower than the native version, but theoretically can run on AMD and Intel graphics cards.
OpenDLSS NR's network weights must be extracted from NVIDIA's closed-source runtime by the user, which is the highest-barrier step in the entire process.
OpenDLSS NR currently has no game integration whatsoever; incorporating it into games would require the community to create mods.
The native version of OpenDLSS NR still requires specific hardware support and cannot run on AMD graphics cards.
