For my Skyrim ENB I'm running SSAO, SSIL, a few particle effects, lots of subsurface scattering, some shadow filters, many water effects like volumetric shadows, caustics and reflections, and some miscellaneous color correction filters similar to Ceejay's shaders on top of the full control over a large portion of the game's rendering. 10% fps loss.
Using Ambient Light, Bloom, or other similar shaders can really drive up the FPS cost in ReShade to be rather absurd for what it is.
What do you mean by "helping"? I've asked for help 2 times and got 2 immediate responses from the ENB dev.
ENB and ReShade are both shader injectors so it's nice to compare and contrast things like the editing GUI, but that's where the similarities end. ENB is entirely built around the game, like Skyrim, where ReShade is made for applying generic effects to any game. I find comparing their effects trivial, personally.
