I see a big difference in your screen shots, but when I tried with something similar—a rock—and took my screenshots—PNGs— with the image at 100%, I'm not seeing it. Looking at a reduced scale isn't ever really accurate, since your aren't displaying 1 image pixel per 1 screen pixel. So maybe that is part of your issue?

Thank you for your answer!But no, I set 25% zooming (I want to photos looks in 25% same zoom in default windows image viewer) and do not zoom after.
Whay image looks different in same zoom?

The preview is sharpening the image already downsampled to 25%.
The final result is applied to the image at the base level, then downsampled to 25% to show you the preview.

Yes, those can differ. You always need to zoom in to 100% to judge the effects, especially on sharpening.

I'm sure Chris Cox has a better answer, but my very  non-technical understanding is the display at 25% is inaccurate because every time, the software has to make a decision about which of 4 pixels to display or something like that. That's why sharpening is always supposed to be viewed for accuracy at 100%.

Yes, yes! But I about problem with visual filling. This post non about professional sharpness. Example: I increase a sharp for more details I can view in standart view. I shows my photos and don't zoom every! :)
