I still get the 10 sec lagg spikes when i got inside Fort Joy but I'm trying to rush through that to go to next act. What i have learned from doing this is that it is directly the save file for your game and specifically the levechace, if this helps the devs or if someone could forward that to them i think that might help. If any of my instructions were not clear just let me know and ill try and make a visual aid of the process. Sadly i think doing this will forever cause that tamper popup that i don't know how to disable.
