Motion Blur: This setting can be enabled in enbeffect.fx by opening the file in any text editor and changing the value of MotionBlurAmount from 0 to 1. The "definition" in-game setting must be set to "off" for this to function.
Detailed Shadows/Skylighting: These can be toggled by setting them from "false" to "true" in the enbseries.ini configuration file.
