Pictures not sharp after opening them in Topaz Studio

I’m converting the RAW files in Lightroom and want to edit a little more in Topaz Studio.
The first thing I noticed, is that the pics are not that sharp in 100% view in Topaz Studio in compare to the Lightroom or Photoshop 100% view. The difference is huge!

I Use TIFF, ProPhoto RGB, 16Bit, 300 DPI. As I open the same TIFF file in Photoshop it’s ok.
Using JPG, I get the same problem: not sharp.

Reset Local Database: no differences
HD Preview: no differences.

Is this a known bug or something?
