CCSRv2 results too different from original image compared to CCSRv1

[pierre1618]

i tried this model with tiles (default values) and i found out that compared to CCSRv1 , the CCSRv2 result change too much from the original image when scales are smaller than 4x, which parameters can i change to achieved that? I already tried to change the guidance scale and prompt but does not improve much .
