I'm contributing my SweetFX profile here as well.
Since I can't take screenshots in game using SweetFX (because it saves pictures in DDS), I will just describe it and then you can test it yourself.
Also, does not work with Fraps, because it uses the same D3D hook for some reason.

(This is a preset taken for Skyrim then edited. No ReShade, just old plain SweetFX)
(Includes my renamed graphics xml for ED if you're curious)
The change is small but subtle.
A slightly increased color using vibrancy settings. (Like the difference between Mass Effect 2 and 3)
A subtle sharpen to make things feel crisp and clear.
A small Chromatic Aberration to make the game feel seen through a quality lense (Very small effect). (The effect is best seen when using the ship lights against a metal surface)
Contrast curve adjustment to remove the gray filter feel of the game.
No AA (I'm a 90s kid, I played games without AA before you were born). Can be activated but counters the lumasharpen a little bit.
(I also use no AA in game)
No vignette, bloom or other crazy effects used, this is a small graphics change.
The change is small when toggled, but it makes the game feel so much vivid.
Performance? Unnoticeable change on the FPS counter in game when you toggle it.
Also works with f.lux.
Use with high texture setting and all effects activated.
Rift users may contribute their opinion on it since I do not know how it looks using Rift.
Enjoy.
