: how to make sims 4 STOP lagging and freezing>
Play Offline – Users have reported that turning off the switch on Origin has tremendously helped resolve their issue. Use the “Origin” tab on the top left corner of the Origin client and select “Go Offline”.
Backup & Remove the Tray Folder – SimsVIP reader Facsimiles has reported that removing the Tray table helped resolve their issue. To access the Tray table go to Documents > Electronic Arts > The Sims 4 > Tray. SAVE A BACKUP OF THIS FOLDER ONTO YOUR DESKTOP. Once you have backed up those files, remove the folder from the Sims 4 game folder. Keep in mind that this folder contains everything you have saved in your Gallery Library, so you will not have those items in your game once you remove the folder.
32 Bit vs 64 Bit – The latest patch reverted some 64 Bit games back to 32 Bit. Open The Sims 4 in Origin and go to Settings > Game Properties > Advanced Launch Options and select the 64bit version. This helped resolve the issue for some.
Remove Mods – Even though the game automatically disabled mods, please be sure that you are running compatible and up to date mods upon enabling mods in the game again. Several mods have been updated or are pending updates since the patch, and outdated mods makes for a problematic game.
