NVIDIA DLSS 5 & NGX Runtimes (Ada Lovelace / RTX 40 Patched)

This repository provides pre-configured NVIDIA DLSS runtime binaries for use with the ComfyUI-DLSS5-VideoSuite extension.

---

🔍 Context & Technical Background

The core component in this repository is nvngx_dlssnr.dll (v310.8.0.0, ~158 MB), which contains the weights and pipeline for DLSS 5 (3D-Guided Neural Rendering / NGX Feature 18).

• Origin: This build originated from the development / early build of NBA 2K27 (which introduced NVIDIA's next-generation neural rendering technology).
• Patch Details: In unmodified builds, NVIDIA display drivers enforce an architecture restriction returning 0xBAD00001 (NVSDK_NGX_Result_FAIL_FeatureNotSupported) on Ada Lovelace (RTX 40 series) and earlier GPUs. This patched build incorporates modifications by the open-source modding community (RenoDX / ReShade) to bypass this check, enabling real-time Feature 18 execution on GeForce RTX 40 Series and RTX 30 Series graphics cards.
