Brush Tool lagging with dot but lines

[Elisefreya]

Hi!!

      I am a photographer and retocuher. I did not have the issue before but now (editing a lot pictures recently). The brush tool and healing brush start to lag and leave dots but lines. I use a lot frequency seperation tech, and the stupid brush toll impacted my work a lot and spend double work time. Any idea to solve? 

     Thanks.

In the Brush Setting panel, what is the Spacing set to?

Hi:

     It's 100% for spacing. I use the color frequency and not very efficient so changed to 100%.   So.. I have to save to 25%?

You will see a preview of what the spacing looks like at the bottom of the Brush Settings dialog box.

100% is too much spacing for what you want.

Even 25% can look a little lumpy sometimes.

Okay. 

 What's the ideal Spacing for like edting and frequency seperation skills?  10%?
