HOW TO - Fix the Lag, at least a bit...

I see a lot of people having this problem, even in a game with no mods or CC at all. It's a problem with the game, the more you play, the more it lags... it started somewhere around the toddler patch.

I'm going to share what I found about it during my messing around with the game.

First thing that makes the Sims stuck:

Idle Animations - emotion idles, ages idles, specific idles like the ones in laundry day, trait idles... these are those little pointless animations the sims do every now and then... they are interactions that run on a clock, sometimes there are many of them that wait to run all together. You can notice this especially when your sims wake up... they sometimes gets stuck, waiting to do 3 or 4 idles all together. Disabling them either with MCCC, SCAM, or any other mod improves the autonomy a bit.

clientDB.package and localthumbcache.package getting too big. Always clean them. 

Then...

A lot of packages in your mod folders - it's not much the size of your mod folders that affects the performance, it's the number of packages you have inside the folder. I have 42 GB CC, my game runs well because those 42 GB are merged into 24 - 25 packages. So if you have a lot of CC, think about making a backup and merging them.

Too many script mods - I had 200. How much is too many depends on your system. You notice this especially with slow autonomy. So if you have mods you don't use just sitting there in your folder, make some cleaning.

Then, lagging and slow autonomy are just problems with the game, so you can try one of the various mods you can find around... I use THIS ONE and it made wonders in my game, but if you have one of the other problems I listed above no mod is going to help and complaining that it doesn't work is pointless.
