There's few DMD2 upscale/refine workflows on this site but all are overcomplicated. Here's the essential simplest workflow presenting how powerful it is. I'm using this stuff at end of all image generation because its simply free 2-5sec, insane, not only upscale, but also subtle fix for every little thing.

At KSampler test with "start_at_step" in 60-68 range. Closer you get to 70 the less impact will it have on photo (less steps). Smaller number - more fixes (more steps) but also more intervention from the checkpoint that you potentially would not like. Input image should be in 768-1280 size. Bigger images can produce mutations like double knees.

DMD2 essential upscaler/refiner workflow is for upscaling and refining an input image; it includes image-scaling and model-based upscaling steps and provides a PreviewImage node for viewing the image output. The description recommends 768–1280 input dimensions.
The graph includes LoadImage, ImageScaleBy, ImageUpscaleWithModel, KSamplerAdvanced, LoRA loading, VAE encoding and decoding, and PreviewImage.
The description suggests resizing an image, upscaling it, and then running KSampler; it also suggests an optional 1xReFocus pass for more aggressive sharpness.
Vorschlag · nicht geprüft
Provide an image through LoadImage; PreviewImage is included to view the image output.
The workflow is published by Luntrix on Civitai as model 1278122.
Before use, verify that the listed model files and workflow nodes are available in your setup.

The workflow lists these model files: 4x_foolhardy_Remacri.pth, bigLove_xl1.safetensors, and dmd2_sdxl_4step_lora_fp16.safetensors.
Listed nodes include CheckpointLoaderSimple, CLIPTextEncode, ImageCASharpening+, ImageScaleBy, ImageUpscaleWithModel, KSamplerAdvanced, LoadImage, LoraLoader, PreviewImage, UpscaleModelLoader, VAEDecode, and VAEEncode.
Try start_at_step values from 60–68 at KSampler. Values closer to 70 are described as having less impact, while smaller values are described as making more fixes with more checkpoint intervention.
Vorschlag · nicht geprüft
For larger inputs, replace “upscale image by” with forced resize so the longest side is no more than 2048.
Vorschlag · nicht geprüft
For more aggressive sharpness, resize the image, pass it through the 1xReFocus upscaler, then run KSampler.
Vorschlag · nicht geprüft
The description warns that images larger than 1280 can produce mutations such as double knees.

To avoid that replace "upscale image by" node with forced resize where longest side is not bigger than 2048.
If you want be more aggressive with sharpness - resize image, pass it trough 1xReFocus upscaler and then do ksampler. https://openmodeldb.info/models/1x-ReFocus-V3
