[nicola15A8]

Hi guys,

it's the first time it happens to me... opening images with photoshop on my new laptop the appear very very noisy... 

If I open the same image with the default windows program it's perfectly clear, the problem is with photoshp maybe some setting must be adjusted but I don't know which one...

can you hel me please?

my notebook is a ryzen 7 4800H with 16Gb Ram and Nvidia Rtx 2060 with 6GB
