Skyrim (Classic) with ReShade and ENBoost

[ENBSeries]

Set all to false under [EFFECT] of enbseries.ini and DeferredRendering=false in enblocal.ini of that preset, then compare performance and report here please.

(edit after writing all this: Welp, seems the main FPS drain here is riverwood itself ^^ maybe EtaC is just pretty taxing here, migth throw Riverwood out, then again, I seemed to get a bit laggy around most villages with ENB and such, maybe turning off ENB just gave it the extra 5 fps to a smooth 30 fps)

So I also got this FPS drop on my normal savegame, but just to make sure I'm made a new character, Let ASLAL send me to Riverwood Inn and then did "coc Riverwood". Walked to my testing spot, let everything settle a little and make a savegame. Then I make a screenshot, quit, change ENB settings, open Skyrim again, load the savegame, wait a bit for everything to settle, make next screenshot and such.

Also posting pictures to show how it looks with the effects, the FPS on the top left, and the testing spot. Not sure how 100% accurate the ENB FPS counter is? But it feels laggy so accurate enough to me.

AMD setings: http://waa.ai/pinky_Edrlz (had Frame Rate Target control set to 30 usually, but disabling for tests) Third or first person doesn't seem to make any difference

Deferred Rendering disabled in all of them.

All effects off / (everything under [EFFECT] in enbseries.ini set to false at least) but UseEffect=true in [GLOBAL] of enbseries.ini
25~26.5 fps

All effects off as before but not UseEffect=false
28.7~29.2 fps

Took vividian config (might have some changes where I turned down the quality of shadow/reflection), then disabled the effects you told me to disable.
25.7~26.2 fps

Vividian config with the effects turned on
22.7~23.2 fps

So yeah, small differences but nothing that goes into "playable".

More tests!

ENBoost mode (didn't disable Enhanced Lighting for ENB, but set inis to non-enb mode)
28.9~29.7 fps... interesting! I seemed to get better fps, but maybe I just assumed the 30-fps cap i had capped it... more tests!

ENBoost mode but with Enhanced Lighting for ENB off
... about the same


So guess the main FPS drain is Riverwood (EtaC too)

[ENBSeries]

Hmm, then i guess it's just because of draw calls amount bottleneck in that place. Did you tried to test that place with ReShade?

[Inari]

Guess there are no magic performance tricks? Got an i5-2500k (but not overclocked so at 3.3 ghz), radeon rx 470 and 16 gb ram.

Maybe I'll try reducing DynDOLOD settings.

Anyway, with just ReShade (so not ENBoost at all, though I don't think the guide I read meant to imply to not use ENBoost) I get 16~17 fps there.

[Inari]

Well turned ENB back on, disabled the effects you said to disable (and DeferredRendering), turned the graphic settings down to medium, put DynDOLOD to Low preset and not I get some 38 fps in that spot.
(Also kicked ASIS out as I don't really need it, but don't think that affected anything)

The shadows are a bit uglier and the draw distance worse obviously. But I guess I'll life with it, at least its playable ^^ And I do much prefer the look of having an ENB. Can probably even turn some effects back on if I don't drop too much FPS then~

[ENBSeries]

The biggest problem of the game is amount of objects drawed on screen, you can see that number in statistics of ENBSeries editor (press Shift+Enter keys, by default). Draw calls bottleneck (with AMD cpu it's much worse) is the big problem for all games, especially dx9 based and earlier versions. Grass mods greatly decrease performance because of this problem, but game itself in some areas is very bad, for example entrance to Whiterun. Reducing drawing distance and distance of shadows affect this bottleneck positively.
Performance of the mod depends from some parameters not listed under [EFFECT] category of enbseries.ini, for example detailed shadows one of them or sky. If you learn to tweak properly to your display resolution, even ssao/ssil will be fast enough to use them. With that bottleneck gpu is not 10)% filled with tasks, so it can be used for heavy effects.
