The farther I get into the game (not even at Diamond city yet) the more drop outs I get. Lowest I've seen was momentarily 26fps while looking through a scope. Normally I get a solid 60. Most drops are only down to 45fps or so which isn't really a big deal. I do have god rays on and everything on ultra, FX 8350@ 4.4 and moderately OC'd GTX970
