Here are the updated logs, I regenerated DynDOLOD and checked that the issue still persists

"So if you start a "new" game with cow whiterunworld 6 0 in console all is fine once DynDOLOD initialized, but saving, existing game, starting game, loading that save has issues?"
Yup, percisely, when I spawn into Whiterun by using Alternate Start (spawning in Bannered Mare, Breezehome or Jorrvaskr and then enter Whiterun) or, when I spawn elsewhere, move to Whiterun, save and exit the game, reload the save I get a massive FPS hit.
Also this FPS hit continues to be in effect even when I exit Whiterun, but if I exit Whiterun and reboot the game and load that save, I would no longer have FPS issues.
As for the DynDOLOD.DLL file, I see that its a dll and pdb file? I installed it and replaced the DLL NG mod, I got the incorrect version error when I loaded into my game.
Thanks again for helping out!
