so I've been trialling Photolab3 and when the images load, it's VERY sharp for a split second and once fully loaded, the images turned out not as sharp. This happens on any image I load.

I've disabled the standard processing that DXO applies but no change to the fully loaded image.

Could I be doing something wrong?

Thanks

I think it briefly shows you an embedded jpeg preview before the main RAW file loads. The embedded jpeg usually seems oversharpened beyond normal.

Which camera and lens? Are these RAW files or JPEG files or possibly TIFF files? Click on the Edit Menu then Preferences and under the General Tab confirm that the Correction settings Presets for RAW files are 1-DXO Standard and for RGB images 4-No Correction

Try zooming in until 80% to get a sense of how sharp the processed image will be. There are several other settings whose effect will only be visible at a zoom setting greater than 80%, like CA corrections.
