Anyone use Skyrim with ultrawide?

[Afro68]

In setting up my skyrim with my ultrawide monitor I'm unsure what my settings ahould be. I'm using flawless widescreen but in setting up my game settings for the enb I want to use I don't get any resolution options. I did edit my ini files for 3440x1440, is that enough.

I have 21:9 2560x1080, but I need Flawless Widescreen to get the gui to fit right:
