I noticed that flux takes far far higher denoising to make any changes for hiresifx but this appears to be related to an issue with denoising for flux. The image is barely changed if below 0.80 denoising.

Would be REALLY nice to have this fixed, as IMG2IMG with flux is essentially pointless with this issue.
