So, I am on my second winter now and am in the process of fighting Klaus, I'm more than well equipped to beat him and know the kiting pattern off by heart at this point. However...about a third of the way into the fight (more or less where he summons krampuses) I start to get an absurd amount of input lag, to the point where the game is virtually unplayable. I suspect it might be server lag, which frustrates me because I'm playing alone and as far as I know there is zero way to play offline. What makes it even more frustrating is that the game runs fine when I first load up the world, the start of the boss is an absolute breeze. Does anyone have any suggestions as how I can fix this?
