You will need ENB. Simply paste this file over the top of the "enbeffectprepass" in the main skyrim folder.

This is my own small tweak to the script for bokeh effect and DOF. I attempted to get it closer to something like Arma II and Darksouls with a softer distant feel rather than the total blur fest the default setting was at.

Please Note: I also have the "realistic lighting" mod installed as well as several others. It's also running without AA since I have a mid tier comp.
