Some of the simmers (including myself) have experienced weird freezing / lagging issues in The Sims 4 since the latest Update. The issue mainly consists of game responding very slowly. For example, it takes me about 10 seconds for the game to react after clicking The Gallery button.
Before I continue with bringing out possible solutions for these issues, please check if any of your mods (considering you have any) are broken!
32bit or 64bit?
It’s possible that, if you’re using the 64bit version of The Sims 4, Origin has reverted it back to 32bit version for The Sims 4. Right click on The Sims 4 game in Origin > Game Properties > Advanced Launch Option and select the 64bit version.
Clear your cache!
It’s important to clear your save game cache every now and then. Go to Electronic Arts > The Sims 4 and delete content from folders that we indicated, including the localthumbcache.package file.
The Tray Folder contains all the downloads and creations you’ve made from The Gallery. By removing the Tray Folder you’ll automatically remove everything you’ve downloaded and created, so if you want to keep your favorite creations and preserve the one’s you’ve made – favorite all the creations you like so you can download them later and upload the creations you like to The Gallery. Removing the Tray Folder fixed all freezing issues for me!
Sometimes being online in The Sims 4 can slow down your gameplay experience. To go offline, go to Origin > Go Offline.
