This a ComfyUI workflow to upscale images to 4K or 8K.
Great for general upscale on photos with Magnific-like results.
This workflow upscales in 3 stages.
The first stage utilizes CCSR - 2x upscale.
Second stage utilizes SUPIR - 4K size.
Third stage utilizes SD ULTIMATE UPSCALE - 8K size.
The workflow is designed to save the result of each stage.
Using a RTX 4090:
First stage and second stage upscale combined takes about 8 minutes.
Running all three stages takes about 18 - 22 minutes.
