How to stop time lag

[123postup]

I didn't know where else to post this so I am posting here and hoping for some help. Does anyone how to fix time lag? What I mean by that is I hit play and it goes ten seconds and then the clock freezes. Then I hit pause and it takes the game a minimum of 15 seconds (I counted) to pause the game and it brings the game clock back about 3 seconds cause I guess that's where the pause registered. The reason I am asking this in here and not somewhere else is cuz I have 128 sims in my game and they all do WW stuff. I hadn't updated the game since the high school years patch. And it was working flawlessly. No lag, simulation or time, and it was really smooth, fps wise. I just updated it and got all the packs that I missed from that point. I have all the packs except for the 2 new kits. And my game is the worst its ever been. And its only really with autonomy on. With autonomy off. the game is as smooth as silk. But autonomy has never been a problem until now. The only mods I use are WW, MCCC, UI cheats, and sim lag fix by srslysims. I just need to know if there is a fix for this, or if I'm doomed to never play how I want to ever again.
