How to add foreground blur to ENBSeries’ depth-of-field in Skyrim

The suggested SkyrimPrefs.ini i was using was the wrong one.

Using Process Monitor i was able to figure out that the correct one is:

%USERPROFILE%\Documents\My Games\Skyrim\SkyrimPrefs.ini

e.g.

C:\Users\Ian\Documents\My Games\Skyrim\SkyrimPrefs.ini

Changing [Controls]\fMouseHeadingSensitivity to

fMouseHeadingSensitivity=0.1250  (new)
fMouseHeadingSensitivity=0.0125  (old)

did the trick.

You can use WASD to navigate through the constellations for each skill. The perk trees are accessed by zooming in to the constellation using W or by clicking.
