In Photoshop CS5 and under, the smudge tool at 100% Strength would drag pixels without smudging/blurring/mixing, creating this cool painting effect. Customizing the smudge tool with a bit of a textured brush shape and some scattering, with 100% smudging Strength would create this amazing painterly effect, but now in Photoshop CS6 the 100% strength does not work. In fact, it works much worse than 99%.
As you can see, at 99% strength, the smudge does less blurring, and more dragging, which is almost as close as Photoshop CS5's 100% smudging strength( it hardly ever blurred or mixed, 100% would only drag in CS5)
100% on CS6 does considerably worse dragging, and alot of blurring, and seems to only be a step above 90%, which blurs and mixes more.
I'm not sure if this is a bug, or if this was an intentional edit to the smudging tool. The smudging tool in the past was completely fine, and now I can't use my smudging tool presets because they do not create the same effects they did when I created them back in CS5.
I checked to see if there were new options or just options I've not seen yet for the smudge tool but it's the same. I also played around alot using the Brush Settings for the smudge tool and there's nothing that affects the drag or smudgeness of the tool. Even without any brush settings, or any other settings (for example, Mode, Sample All Layers, Finger Painting, and the Size Pressure button) the smudge tool will drag alot more with 99% than 100%.
