Mac (1.6.3 ) My game is stuttering after patch

[MissLissaDay]

I have 1,600+ hours in this game and have never had this problem before. (My current game is unmodded) I was in the first year of my game when I updated to 1.6 and it worked perfectly fine there were no problems at all. But after the 1.6.3 patch, my game started stuttering. It wasn't too bad at first so I kept playing but the more days I played the worse it seemed to get and now even the music hitches when the game stutters. I play this game when I go through intense periods of stress and I REALLY need this game right now. Please help.

I have been running into the same issues. Even my mouse is moving slowly since the newest update and after about 20 in-game days it's virtually unplayable for me.
