Sims 4 Unplayable: Laggy Save.

@puzzlezaddict The size of the new save file is this one. I made it yesterday, but had to take it out to try the solution your offered. I just got out of the game, the lag in the last save file from October is extremely slow, it's insane. I don't know why it happened, but in the new save file I noticed it runs as it is expected for this gaming computer even with CC/Mod and if you compare the size I uploaded here (yesterday) in the previous page, then you might see the size it is wayy bigger. This never happened before so I am confused about what might happen. But, anyway... Thank you so much! I really appreciate the help you provided!

Yeah I might keep the backup, but I don't mind starting fresh from time to time 🙂 By the way how do I delete homelesss? Do I have to do it all by myself despite having MCC?

@Simtasticgallery  To delete the homeless sims, you need MC Cheats as well as the base module.  Load a household, pause the game, click on the mailbox, choose MC Cheats > Deletion Cheats, and deleting the homeless should be one of the options.  If there are homeless sims you want to spare, be sure to move them into houses, at least temporarily, before you do this.

I'm not totally sure this will fix the issue, but like I said, it's easy enough to quit without saving if you don't like the results.  You can also use "save as" and rename the save afterwards: see how the save runs going forward, and if you don't think there's enough of an improvement, your previous save file will still be intact.

I know this thread is old and idk if my problem is the same as yours but whenever I play a save for a while the game starts getting lag. When moving the screen around it moves slow, clicking on items the bubbles take a few more seconds to pop up. The game gets unplayable and I end up having to start a new save and the problem goes away, so I know it isn’t mods or cc. I’ve also tried playing the same save without cc and mods and it will still be super slow. I know in Sims 3 there were files you could delete to free up that lag, so I was curious if there was also a way to do that in the Sims 4

@Hailey_love_13  There are a number of different causes of lag in Sims 4.  To start, please run a dxdiag and attach it to a post.

Please also let me know how long you've been playing your affected saves, and how large the save files are in size.  You can see them in Documents\Electronic Arts\The Sims 4\saves.

I was actually able to figure it out. Deleting some cache, localthumb files and the last exception files seemed to fix the problem!
