My third preset.. Combining ELFX with ELE for a pretty looking skyrim that rivalled some of the ENB presets, without the huge drop in performance.

Requirement Mod (Tweaks are done based on these mods)
1) Pure Weather - For Exterior Lighting, and probably IMHO the best weather mod in Skyrim
2) ELFX - Interior light bulb, adds light source where it make sense.
3) ELE - The main mod for interior lighting. Normalized imagespace. Hard to explained, and while its main focus is for ENB, it work as flawlessly for non ENB setting such as this too.

Recommended Mod (Not Required, but they are capable replacement for ENB modules which arent available to sweetfx users)
1) Sun Glare  A texture replacement for ENB GodRay.
2) Dynavision Providing DoF effect, without the fps loss; also get the unofficial dynavision patch for the static mod awesomeness.
