Nvidia_RTX_Deblur_Denoise_ComfyUI

Two GPU-accelerated post-processing nodes for ComfyUI powered by NVIDIA RTX technology via the nvvfx SDK. Only works on NVIDIA RTX GPUs.

This is a ComfyUI port of the Deblur and Denoise features from sd-forge-nvidia-vfx by Haoming02. Only these two features have been ported as a custom node pack for ComfyUI.

Nodes

RTX Deblur (image/postprocessing)

Corrects blur and softness in images using NVIDIA's AI deblur model. Output is the same resolution as input.

RTX Denoise (image/postprocessing)

Removes noise and grain from images using NVIDIA's AI denoise model. Output is the same resolution as input.

Quality Levels (both nodes)

Level	Description
Light	Minimal correction, preserves most original texture
Moderate	Balanced (default)
Aggressive	Stronger correction
Maximum	Strongest correction, may over-process

Requirements

• NVIDIA RTX GPU
• nvidia-vfx Python package

Installation

1. Place this folder in your ComfyUI custom_nodes/ directory
2. Restart ComfyUI
3. Search "RTX Deblur" or "RTX Denoise" in the node browser under image/postprocessing

Example Workflows

Basic deblur: LoadImage → RTX Deblur (Moderate) → SaveImage

Basic denoise: LoadImage → RTX Denoise (Light) → SaveImage

Combined: LoadImage → RTX Denoise (Moderate) → RTX Deblur (Moderate) → SaveImage

Notes

• Both nodes use zero-copy GPU memory sharing via DLPack — tensors stay on the GPU throughout
• Batch processing is supported; batches are automatically split to fit within GPU memory limits
• These are distinct from the RTXVideoSuperResolution node — they do not change image dimensions

Credits

• Original implementation by Haoming02 — sd-forge-nvidia-vfx
• This project ports the Deblur and Denoise features from that extension into a standalone ComfyUI custom node pack
