Preformance loss with nothing enabled/optimization

[jabberwockxeno]

Even if I turn everything in the ENB off, I only gain around 2 -3 FPS. But if I turn the ENB off itself, I get like 15 - 20 FPS. I don't know if this is normal, but I can't imagine it is. Indoors, I get a smooth 60FPS no mater what I do.

Regardless, if there's anything I should have disabled or a setting that I should adjust to squeeze some more fps out of ENB, here's my Enbseries file:

i'm having the exact same problem:
my specs are:
amd phenon II x4 965 be 3.4Ghz
xfx hd 6850
2x4GB Ram 1600Mhz
1360 x 768 resolution
using realvision enb with the 0.155 dll

everything is on high setting with fxaa(from skyrim) enabled + anitrosopic filtering (from enb) ~~ (anti aliasing from skyrim disabled)

i have 2k textures mod + bethesda hd pack
lush trees and grass
skyrim flora overhaul
realistic lighting
climates of tamriel
other mods don't affect fps

so, with these settings i run skyrim at 60fps in dungeons, 50-60 cities and 40-50 in very very grass areas.When i activate effects on enb with all the effects except dof and ssao i get 25-35 fps in most areas.disabling EVERY EFFECT simple gains me 2-3 fps boost.
is this normal?is there some configuration that i'm missing?
thanks in advance

Edit: forgot to mention,sorry for my english
