I can confirm this behaviour. If the input image has noise and a high pixel count, upscaling makes the noise noticeably more apparent—the results are comparable with the much faster lanczos upscaling used by image magic. (On my Ryzen 5 4600H, it takes 20–30s for waifu to complete the operation, compared to ~3s for image magic.) This is the image I am using:
Even moderately sized images (I tested 1500x2500 png) had almost no denoising at
-n 3
.Might be good to add an option for small, medium and large images as well as multi-pass.
Small images it works pretty good. Very fast.
For working with large images (2k-10k) it's pretty useless. Probably due to how the original non-vulkan version works, though I haven't tested it.
