I've always played Skyrim on PS3 but now I'm moving to PC, so I've taken the save form the console and put it on my computer. The problem is that when it loads, it's completely lagged, it takes seconds to move for example. In my PS3 I have the normal Skyrim with the 3 DLC's installed and in the PC i have the Legendary Edition, perhaps that's the problem. Anyway, if I disable Dragonborn DLC it remains the same, the same happens if I disable Hearthfire, but when I disable Dawnguard it runs fine. If I turn on DragonBorn and Hearthfire it remains running fine, but if I change the scenario (fast travel or entering a building) the game crashes and closes (The same happens if I only set Dawnguard enabled) I tried installing Skyrim Script Extender and I didn't manage to get it working. I installed all four "Unnofficial" Skyrim Patches from Nexus Mods and nothing happened. I don't really know what can be happening, becouse I started a new game (and advanced in the game as well) and it works just fine.
Anyone know anything about it?
