Same, game runs beyond slow once you reach a certain time period in the game, after that it's just a massive lag that prevents anything from being done, i can turn autosave off and it stops the stuttering but only outside of dungeons, however should i try to manually save, i might as well walk away from my pc for an hour cause it bricks the game and takes my pc to a screeching halt, if a solution is found plz lemme know.
