HOW TO REVERT A SAVE/GAME TO A PREVIOUS/LOWER UGRIDSTOLOAD VALUE
This is a very brief method of what is required to revert to the default or LOWER ugrids if you have decided the higher value your using is to much.... but don't want to start the game over or go back to a save hours/days/months when you were running a lower one.
1: Start the game with the current ugrids value..
2: Load the save game that you'd like to revert/change back.
3: Once the game is loaded, ALT+TAB or minimize the game.
4: Navigate to your Skyrim.ini file located typically in the documents/my games/skyrim/
5: Input the Ugrids value you'd like to use, DEFAULT is "5", otherwise if you want to go from 9 down to 7, put in 7.
6: Save the file and then maximize/tab back into skyrim that is already running.
7: hit the "~"/console key and type in "refreshini"
8: Save the game as a new save file.
