Yeah, I tried both, and while they are neat, it just shows how bad the game actually is. Both mods are just like tries to repair a broken mirror or bottle.
Particularly this civil war overhaul mod always broke my game. Always. Fresh install, new game, old save files didn't matter what I tried. I always had situations where it broke quests, so much that I could not even advance with the console. It simply shows how shitty Beth is with their coding and scripting - I mean I don't even blame it all on the modder, it does apparantly work for some. However, even this mod could not change the shitty writing of the game or hide the fact that the game was simply not made for this super-massive-dragon-origins type of battles. Even in civil war overhaul you never see more than 10 or 20 NPCs on your screen. For obvious reasons.
Maybe, if they achieved something like this
Now we are talking WAR.
But that's just a pipe dream. Bethesdas engine can't even work properly with the low numbers of NPCs you have right now. It would melt 90% of the PCs out there if they even tried to get it to behave like in that video. And I feel this has less to do with the hardware, but more with how badly optimised the engine actually is. And that after Beth has 15 years of experience in programming ...
