Is it me or is there a recent issue where Photo AI’s Sharpen output is damping down some definition. Most noticable in landscape photos.
Nothing changed in the latest AI versions for the Sharpen Models, it’s the same models and cannot give different results. Make sure your graphic card is updated to the latest drivers! SEnd us exemples and your original file to support@topazlabs.com or here, and we can have a look too
