Before you do SD upscale, you need to do a latent upscale. You want to sharpen a sharp image, not polish a turd. Set controlnet to inpaint. Select inpaint + lama. Set strength to 0.75 set denoise to 0.5. Also set to resize “by” not to. Then resize by 1.5 or 2. I use 1.5. Generate that without Ultimate Upscale. Then drag result to the img2img section. Change denoise to 0.2-0.3. I use 0.3. Change controlnet to tile. Now use Ultimate up-scale and upscale by 1.5 or 2, not 4. I use 1.5. Completely deleted your positive prompt and leave the negative. Hit generate. Now drag that result in and change nothing. Generate again. Now you have a perfectly upscaled sharp image that needs no additional work. If you want, you can repeat 1 more time but it’s overkill at that point, unless you need a 6000 X 6000 image for some odd reason…

There are already tutorials showcasing this technique. StableSR on the other hand seems very good for upscaling an image with very little change. It's apparently often used with Tiled Diffusion, but there isn't a single tutorial for either.

Thanks for the video! I'm surprised you didn't get a lot more artifacts with your noise set to 0.75. I can't go any higher than 0.2. I also find that DPM++ 2M Karras works the best no matter what sampler I use for the TXT2IMG.

The strange thing I have is that when I use an already created png image that I created with a faceswap, still when starting SD fresh and loading that already created PNG file and start the upscaling, it then makes everything sharper (and larger) but somehow the custom face is gone and it puts back some AI face. What am I doing wrong?

What grafic card you use?

Testing right now. Seems to be very helpful for me with my GTX 1070... It takes ages - but hopefully the result counterbalance this...

I like your videos so much. Can you teach us how to make our own model. Like generate our own photos by giving the prompt in stable diffusion.

does this tool can remove pixlated images

You sound so unbelievably german xD

schwätz doch deutsch xD

I'm still getting better results from hires fix, but I'm making progress with tiling. One thing this video doesn't mention is denoise strength. I lowered it to 25 and got a decent result. Unless I'm missing something 75 in your video? I tried it, and it looked baad.
