you may add some screenshots of the problem for better explanation but anyways try placing the ini settings provided by HeyYou in the Fallout4Custom.ini. Also about the SSAO and Anisotropic filter settings in the launcher if using ENB: I am not sure about the Anisotropic filter but if you turn on SSAO in the launcher as well as in the ENB, you are actually applying the effect two times on the scene, eating-up your fps. That means choose only one SSAO, vanilla or ENB
