Where is my sims 4 cache folder?

It is NOT a folder it is called this localthumbcache.package
There is also a folder called cachestr. and one called onlinethumbnailcache. You have to delete the one in bold.
The place to look for this file is in Documents/ Electronic Arts/ The sims 4 there you have all the different folders and under the folders a whole list of other stuff. amongst those you will find the localthumbcache.package

Hope it helped

I dont have this...

I already deleted what you have mentioned and the game is still extremely slow, yesterday was very fast

it is the bottom one, next to game version.

The game running slow is not necessarily due to the caches file. Did you install anything new since yesterday? I am not really computer savvy, Tarac or the ghostman are most definitely the guys who might be able to help.

Jip i deleted localthumbcache, but the cache folder above videocamerastates is what im missing, sure if i can find it, and delete the cache, the game will be as fast as yesterday
Although dont know where to find this folder as theres no such folder in my documents, elect arts, sims 4,even when enabling show hidden folders

Nope, i had lots of mods yesterday, and today i deleted unnecessary mods, so actually should run better
I definitely think its cache as i played long yesterday(the longest i have played since got the game)

Try renaming the folder (My Documents\Electronic Arts\The Sims 4) and forcing the game to recreate the entire folder.

Then you can copy the mods, saves, etc you still want to use from the renamed folder to the new one. I would suggest only a few at a time to see if they cause any issues.

The Origin cache consists of a couple of folders.
To clear the cache:

1. Hold Windowskey down and type R
   
2. In the window type %ProgramData% and click on OK  (so including the %)
   
3. Open the folder Origin
   
4. Delete everything except folder LocalContent
   
5. Again hold Windowskey down and type R
   
6. In the window now type %AppData% and click OK
   
7. Delete the folder Origin
   
8. Click in the path indicator ->Appdata ->Roaming on AppData
   
9. Open the folder Local and delete the folder Origin
   
10. Reboot the computer.

I completely forgot that about the Origin version having those extra caches. Thanks for the reminder @Tarac
