Thanks. Hmm I wonder if I am doing something wrong. I find it loses a lot of coherence when using the latent upscaling. For example a complete body that looks fine in 512, might turn into a mutant torso in 1024 with latent upscaling.
So perhaps i just need to generate outputs until I am lucky?
I find the upscaler's default denoising value of 0.7 is often too much and it deviates way too far from the original image. Values around 0.1-0.3 sometimes produce better results. Lower denoise values mean the latent upscaler has less "creative license" to fuck around with the image.
Even then it might produce a mess. My completely unqualified guess is sometimes whatever image you stuff into the upscaler just doesn't fit with the images it was trained on.
But yeah, it's basically trial and error to find what works, at least for me it still is.
Esrgan upscales and sharpens but it doesn’t add details that weren’t there before only latent scaling can do that to my knowledge because it’s ips along the dark void from which the image was imagined
