I also successfully applied DynDOLOD by Sheson. The same guy that "fixed" Skyrim with the memory patch. It takes some effort to do this. Preparation is key. But the result is great. I picked the "high" option and generated full detailed LOD with all LOD objects. The big difference is that you will see objects from a distance and that all the colors match. This is because the LODs are made with your modlist. It took my Skylake PC 45 minutes to calculate all the LODs. And i had to do it 3x, as Open Cities takes some additional effort.
With the game on a 7x7 grid, instead of the default 5x5 and these awesome LODs, it just looks incredible. This is also the max i can squeeze out of Skyrim. Even with a powerful PC you do notice some small FPS drops. But the views have improved a lot.
Maybe for a performance setup it is best to select the medium option. But i'm fine with the current results.

This allows you to change the grids in the INI. More than 7 is not adviced as the larger grid also activates events earlier.
