I'm also getting a generally choppy experience with annoying 8 sec long freezes.
I tried de-activating all of my mods, verifying the game cache, turning the settings down, nothing happened.
I checked my saved games folder, all of my saves are under 6 mb.
What's up with this? It was all working great and now after removing a mod the game's simply unplayable! Any help would be hugely appreciated.
