NOTE: as for the Recommended adjustments section, SSE Engine Fixes (skse64 plugin)[www.nexusmods.com] is recommended instead of Achievement Mods Enabler by xSHADOWMANx, as not only does it re-enable achievements, it also fixes issues with the game engine.

DynDOLOD enhances the game by generating more detailed and inclusive LOD (Level of Detail) for distant objects in the game which otherwise would either not be visible or of extremely low quality, as well as eliminating "pop-ins" - where an object will suddenly appear where nothing was visible before, when you are moving.
