OpenDLSS reimplements Nvidia's DLSS 5 neural rendering network in Vulkan, bit-exact
OpenDLSS: A Vulkan Reimplementation of Nvidia's DLSS 5 Neural Rendering Network

A Vulkan reimplementation of Nvidia's DLSS 5 neural rendering network, matching the original bit-for-bit. The same 71-block Swin/ViT network runs FP8 on tensor cores, with all 75 block boundaries byte-identical. A WebGPU port achieves the same exactness in a browser without tensor cores or FP8. You supply the weights. Performance reaches 2.8 ms at 768x768 on an RTX 4070 SUPER.
The exactness is in the specification, not in the hardware.
