ComfyUI-PIX_Nvidia_RTX_Deblur_Denoise

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
