9 Ways Fixing Simulation Lag in Sims 4

If you are experiencing simulation lag, there are a number of things you can do to fix it.

Fix 1: In-game settings

The first thing you should try is lowering your graphics settings. You can also disable unnecessary features, such as uncompressed Sim textures and post-processing effects. Reducing the size of your world and limiting the number of Sims in your household can also help to reduce simulation lag.

Fix 2: Mods and custom content

If you use mods and custom content, try disabling them one by one to see if that fixes the problem. You can also try installing the Simulation Lag Fix mod.

If you’re playing The Sims 4 and experiencing slow gameplay, don’t worry, you’re not alone. There are some mods that can help you speed things up. SrslySims and Coolspear have made some mods that target simulation lag, which work great with TurboDriver’s mod. But, having too much custom content can also slow down the game. So, you might want to go through your custom content folder and remove some of the larger files to speed up the game.

Fix 3: Simulation Unclogged

The initial mod mentioned is “Simulation Unclogger” by TurboDriver, which helps prevent the game from freezing and crashing but doesn’t entirely fix simulation lag.

Fix 4: Backup and Remove Old Saves

Backing up your saves and removing old saves from your game folder might improve performance. Sometimes, old saves can cause issues.

So this is the technique that I am possibly trying for the game lags, and it actually works out most of the time, so if you are facing the simulation lag in Sims 4 or Sims 3 you can try this. 

Fix 5: Library and Tray Folder

The Library is where your saved builds are stored locally, and the Tray folder contains items from the Gallery. Removing unnecessary items from these folders might help with lag.

Fix 6: Try Playing Without Mods

To diagnose if mods are causing the issue, you can temporarily play the game without any mods. This can help determine if mods are contributing to the lag.

If you are using modes in the simulation and Sims 3 or in Sims 4 then definitely you should try not using it once if you figure out that by not using it you can reduce the lag in the game then that’s an advantage. 

Fix 7: Autonomy and Inventory

Turning off autonomy for Sims and ensuring inventories are not overly cluttered can reduce lag.

Fix 8: Single-Core CPU Issue

Some players mentioned that The Sims 4 utilizes a single core of a multi-core CPU, potentially causing performance issues.

Fix 9: Xbox Lag

If you’re experiencing lag on Xbox, there may not be as much you can do in terms of mods. Ensure your console is updated, and you might want to consider limiting the number of Sims and households in your game.
