Now I use ugrids 7 with the open cities mod, however since skyrim wasn't really meant for any ugrids above 5, Im thinking of maybe getting my game back to ugrids 5 and seeing if I can add a mod that simulates a higher ugrid setting.

So Enhanced Distant Terrain - http://skyrim.nexusmods.com/mods/1598/? & Skyrim Distance Overhaul - http://skyrim.nexusmods.com/mods/19446

What I want to know is what the quality of those 2 mods are like compared to ugrids 7 and/or 9 are.

Are they equal or greater than a higher than default ugrids setting? Is there less chance they will crash the game as in a higher ugrids and can they be used with Open Cities decently?
