Just saw an ENB mod thread in general section. That reminds me, have you guys checked this awesome graphical mod. After applying it, you can surely never want to see vanilla SKYRIM ever again.
MOD comes with usual multiple jaw dropping configurations. The best thing, it has not more then 5 frame drop rate, even less with super elite rigs.
Modes Cinema, Darker Nights, Vivid, Balanced
