Weird shadow lines with ENB

[mememan69]

Tried using an ENB in Fallout 3 for the first time the other day and had these weird lines that created straight shadows whenever I moved. Was wondering what the cause was/how to fix.

 

Also, whenever I looked up into the sky, the game would freeze for a few seconds.

 

Thanks!
