The Sims 3 Performance & Bug Fix Guide 2025

This is a guide on how to make The Sims 3 run smoother, use mods to fix un-patched bugs and fix some compatibility issues on newer gaming PC hardware and systems.

Introduction

Hello!

Welcome to my guide for The Sims 3 and how to improve its performance on newer PC systems. Every step that I have listed are the steps I personally use to make my game run much more smoother on my PC system.

If a step has an "(Optional)" tag in the title means its up to you if you would like to add the tweaks to your game, If it has a "(Essential)" Tag in the title it is recommended that you use the step to get the best results with the game and its performance.

If you have any questions feel free to look at the F.A.Q Section for common questions that have been answered.

Happy Simming!!

This guide is intended to be used with game version 1.67 Steam and 1.69 EA App on Windows 10 OS and Windows 11 OS, this guide was not made to be used with the game version 1.70 (64 bit Mac Update). Edit at your own risk if using game version 1.70.

Versions obtained without purchase are not supported at all!

Getting Started!

A FRESH CLEAN INSTALL OF THE GAME IS HIGHLY RECOMMENDED!

A BRAND NEW SAVE IS ALSO RECOMMENDED!

Removing certain scripting mods on an already existing save file can lead to corruption in the save file.

Installing The Mods Folder

For new users to The Sims 3 Modding this will show you how to install the Mods Folder into your game so your game will be able to read and use ".Package" file mods.

The "Mods" Folder is for .package files, .sims3pack Files need to be installed through the games launcher. I recommend this depth video by @SimMattically for more information about the different package types can be found HERE!
　
Step 1 - Download the mods folder using the download button from ModTheSims HERE![modthesims.info]
　
Once on the download page scroll down a little until you see a "Download" button, once found click on this link and it will download the file.

After the download is complete place the file somewhere easy to find like the desktop.
　
Step 2 - Once downloaded go to...
　
"Documents\Electronic Arts\The Sims 3"
　
Once there, open up the downloaded mods folder file and extract its contents right into The Sims 3 documents folder.
　
Step 4 - Just to make sure open up the mods folder and make sure the contents inside looks like this image below!
Files that should be present and that are needed are...

• Resource.cfg File
  
• Packages Folder
  
• Overrides Folder

　
The two package files that come inside the packages folder called...

• NoBuildSparkles.package
  
• nointro.package

these files are for testing purposes only and can be safely deleted after launching the game to see if the mods folder is functioning correctly.

If the maxis logo is still showing up on startup even with the "nointro.package" present in the mods folder for testing this is normal since the "nointro.package" was made before that intro screen was added in a later patch and uses a different file path to the other intro videos.

　
　
If you want to keep "nointro.package" to disable the intros and want the Maxis Logo Intro gone as well, you can download a mod for it HERE[modthesims.info] to be used along side "nointro.package".
　

　　　　　　　　　　　　　　

The Mods folder is now installed!

Step 1 - Making The Game Recognise Newer GPU Models (Essential)

The Sims 3 GPU Add-on Support TOOL

With The Sims 3 releasing back in 2009 and finishing its run in 2014 newer models of GPUs have come out since then but since the game has not been updated by EA due to no more patch support the game will not recognise newer graphics card models and believe it or not make you game run slower.

Making the game recognise newer GPU models will benefit in less lag spikes in game-play performance since the game will use the newer cards benefits since its knows the cards model.

The Sims 3 by default can only recognise cards from GeForce 600 series and under if you have any of these cards currently installed into your PC from these Desktop series or if the game is installed on Steam Deck...

• GeForce 700 Series
  
• GeForce 800 Series
  
• GeForce 900 Series
  
• GeForce 1000 Series
  
• RTX 2000 Series
  
• RTX 3000 Series
  
• RTX 4000 Series
  
• RTX 5000 Series
  
• GTX Titan Series
  
• Steam Deck

You will need to use the tool!

It might work for AMD Cards if not check how to manually edit with the link down below.

Step 2 - Lazy Duchess Mods

Here are some essential mods made by Lazy Duchess, these are must have's and after installing them I can not play without them!

Smooth Patch 2.1 (Essential)

Smooth Patch by Lazyduchess alters the speed at which the game's processing runs, which improves the overall performance of the game and some loading times. Most noticeably in Create A Sim, Create A Style and Buy/Build.

This ONLY works on the Steam version (1.67), Disk Versions and EA App version (1.69) of the game (1.0.631 to 1.67). latest MAC versions (1.70) will not work.

Step 1: Download the mod from HERE[modthesims.info]

Step 2: Open the downloaded archive and locate you Sims 3 game directory. It should be under...
　
Steam 1.67 - "Steam\steamapps\common\The Sims 3\Game\Bin"
　
EA App 1.69 - "EA Games\The Sims 3\Game\Bin"

Step 3: Simply drag and drop these three files from the downloaded archive...

• TS3Patch.txt
  
• TS3Patch.asi
  
• wininet.dll

into the games "bin" Folder.
　

　
Step 5: Smooth Patch 2.0 Is installed!

Installing the "ld_SmoothPatch.package" file is optional as sometimes you may encounter bugs using it with Nraas Master Controller CAS or mods that make changes to CAS. The .asi and .dll part of the mod is 100% fine to use!

　

Bonus Step: Faster Smooth Patch Settings

If smooth patch does not feel smooth enough you can tweak the tps limit higher, its recommended that you only adjust the speed settings if you are on a gaming PC!
　
Step 1: Locate "TS3Patch.txt" in the games directory and then open the ".txt" file.
　
　
Step 2: Locate the line "TPS = 500" and change the "500" to "1000".
　














Step 3: Save the document and exit notepad.

Bonus Step: Window Border-less Mode

Window Border-less is great for people who have multiple screen setups or just like alt + tab out of their games! Sims 3 by default has issues with multi screen and alt + tab. It can also fix the miss coloured/dark capturing of the game when screen recording or streaming!

Step 1: While "TS3Patch.txt" is still open go the to option "Borderless =" and change the "0" to a "1", next save the document!
　
　
Step 2: While in game make sure to go into setting and set the display-mode to windowed mode!







Once the settings is unchecked make sure to press accept at the bottom of the settings menu! The game is now in border-less windowed mode!

Intel Alder Lake Patch (Essential) (Steam 1.67 ONLY!)

Intel Alder Lake Patch by Lazyduchess is a very simple patch that attempts to workaround the crash on boot when trying to launch The Sims 3 on Intel alder lake CPU's (12th gen) or higher.

If you are using a 12th gen Intel Alder Lake CPU or higher you will need this patch so that The Sims 3 Will Launch on Start up! If you do not have this version of CPU you can skip this section!

Download the Intel Alder Lake Patch By Lazyduchess HERE[modthesims.info]!
　
Step 1: Once downloaded place the patcher into a file on your desktop for easy access.
　
Step 2: Once place into the folder run the program and press "OK" on the window popup.
　
A New window will open it should already be at your games bin folder but if it is not you can find them at the provided file path below.
　
Steam 1.67 - "Steam\steamapps\common\The Sims 3\Game\Bin"
　
Once the new window has opened select the .exe files called "TS3.exe" and "TS3W.exe patching one at a time"
　
Step 3: Once accepting the patching a new little popup should appear saying the patch has been applied and was a sucsess, press "OK" and you are done.
　
Once patched by the program close the program and your game is now ready to be used with Alder Lake CPU's. The program will also create a backup of the games .exe that was patched just in case!

Mono Patcher Library 0.3.0 (Essential)

Mono Patcher is a library that allows Script Modders to replace Sims 3 methods with as much compatibility as possible - No need to create core mods anymore to replace game functions.
　
Step 1: Download Mono Patcher Library from...

Mod The Sims - HERE![modthesims.info]

Github - HERE![github.com]
　
Step 2: Once downloaded go to your games mods folder located at...
　
"Documents\Electronic Arts\The Sims 3"
　
Once inside the Mods folder open up the "Packages" folder and create a new folder.
　
After creating the new folder place the "ld_MonoPatcher.package" file inside the newly created folder.
　
Step 3: Once that is done you will need to go to the games "Bin" Folder in the games install directory, it can be found at...
　
Steam 1.67 - "Steam\steamapps\common\The Sims 3\Game\Bin"
　　
EA App 1.69 - "EA Games\The Sims 3\Game\Bin"
　
Once there place the files "wininet.dll" and "MonoPatcher.asi" into the "Bin" folder in the games directory. Overwrite files if necessary.
　
Step 4: Mono Patcher Library is now installed.

Step 3 - Nraas Mods (Essential)

Nraas mods will help your game run smoother and less likely to crash.

These Mods will be installed into your games "Mods" folder found at...

"Documents\Electronic Arts\The Sims 3\mods\Packages"


Here are the Nraas mods that are needed to make the game more stable...

• Nraas Error Trap[www.nraas.net] - Error Trap is a mod that detects and catches corrupted data and lets save games be loaded/played and preventing crashes, Error trap will also create logs within the games documents folders to help narrow down the error cause.
  
  

  EA App users download using this button!

  
  
  

  Steam users download using this button!

  
  
  Note: Only Error trap requires different download buttons for different game versions, all other Nraas mods use the same download button.
  　
  　
  
• Nraas Overwatch[www.nraas.net] - Overwatch resets stuck sims and puts them back to their home lot safely will also remove unused cars that slow down the game, turn off stereos that are not in use on non played sims homes ect.
  
  
• Nraas Master Controller [www.nraas.net]- Lets you become more of a god with option to set slider values edit any sims in CAS set skill levels and so on can also be used to reset lots and sims manually even an entire town to fix any issues.
  
  
• Nraas Register[www.nraas.net] - Allows the user to disable certain classes of npc's within town things such as paparazi's, strays, wild horses, unicorns and much more! This can help big with performance in worlds such as isla paradiso were horses cause lots of lag when spawned in by the game.

Step 4 - Simler90's Gameplay Core Mod (Essential)

Simler90's Gameplay Core Mod fixes a long list of issue and bugs with the base game and many of the expansion packs.

Some of the bug fixes included are...

• Bonehilda will now take care of children and toddlers correctly!
  
• Child and Teen now can attend school while grounded, no more sneaking out to school!

Step 1: Download Simler90's Gameplay Core Mod HERE[modthesims.info] and place it in the folder at...
　
"Documents\Electronic Arts\The Sims 3\mods\Packages".
　
　
　
　
Step 2: Next while in game you will need to change a setting for Nraas Overwatch so that some mod functions do not overlap while playing between Nraas overwatch and Simler90's Core Mod.

• While in game find the City hall rabbit hole in your save and click on it.
  　
  
• Once the city hall rabbit hole has been selected you will need to go to "Nraas > Overwatch > Settings > Set Alarm Hour".
  　
  
• A New window will popup with a defualt time of "3" this needs to be changed to "5", once changed press the check mark icon to accept the changes.
  
  Disclaimer: This will need on be done on every brand new save.

　

DISCLAIMER! - Nraas forums will not offer support to users who have Simlers90's Core Mod installed if reporting issues with Nraas mods to them on their official forums. More information HERE[www.nraas.net].

Step 5 - Limiting FPS (Essential)

Limiting the game to only use your monitors refresh rate will increase game performance dramatically. The reason being is that the engine The Sims 3 runs on runs at an unlimited FPS with no built in frame limiter! This is why most PC's sound like they are taking flight from an airport runway when playing. Not limiting the games FPS can decrease the life of your graphics card fans!
　

How to limit the games FPS

　
Step 1: Right click the desktop and click on "Nvidia Control Panel".
　


　
　
Once the control panel opens click on the tab "Manage 3D settings"
　



































　
After clicking make sure that the application selected is "ts3w.exe"
　
　
　
　
Step 2 - Once confiming that ts3w.exe is selected find the option "Max Frame Limit". Once there click the option and select "on" once selected put in your monitors refresh rate and then press "Ok".
　
　
Step 5 - Next you will need to select the option "Vertical Sync", once slected click on the option "on".
　
⠀⠀⠀⠀
Step 6: Once all done make sure to press the "Apply" Button at the bottom of the window to accept and apply the changes!
　
　
　
　

If you don't have an Nvidia GPU or a graphics card control panel Smooth Patch has an in built frame limiter!

　
Go to "Steam\steamapps\common\The Sims 3\Game\Bin"
　
Then you will need to open "TS3Patch.txt" once open replace the "0" next to "FPSLimit =" with your monitors refresh rate then save the document!
　

If the game is freezing at startup change "FPSLimit = " back to 0 and use you graphics card control panel instead or another frame limiter software.

　
　

Step 6 - Making The Game Use More CPU (Optional)

If you are using a PC with a low end CPU or a PC that is not meant for gaming this step should be skipped!

Step 1 - Locate "GraphicsRules.sgr" at...

Steam 1.67 - "Steam\steamapps\common\The Sims 3\Game\Bin"
　
EA App 1.69 - "EA Games\The Sims 3\Game\Bin"

Once there open "GraphicsRules.sgr" in notepad (or notepad ++ makes things easier to edit and find)

Step 2 - When opened press "Crtl + f" a search bar will appear type in the search bar "seti cpuLevelUber" and press enter.

Step 3 - When located Change the numbers 3,2,1 all to the number 3

From This


To This


Step 4 - Save and exit the document.

Step 7 - Making The Game Use More Vram (Optional)

Step 1 - Locate "GraphicsRules.sgr" at...

Steam 1.67 - "Steam\steamapps\common\The Sims 3\Game\Bin"
　
EA App 1.69 - "EA Games\The Sims 3\Game\Bin"

Once there open "GraphicsRules.sgr" in notepad (or notepad ++ makes things easier to edit and find)

Step 2 - When opened press "Crtl + f" a search bar will appear type in the search bar "seti textureMemory" and press enter.

Step 3 - When located Change the number that is next to "seti textureMemory" you will see the number "2048" (2gb) this can be changed to the number value of "4096" (4gb). If the number is already at "4096" no changes are needed, setting the value any higher may not take effect due to the games 32bit nature.

Step 4 - Save and exit the document.

Note - If your PC does not have a dedicated graphics card leave the value at "32"..

Step 8 - Cleaning DCBackup Folder (Essential)

When installing things through the launcher the path to those files are saved in this file but of course there are a lot of files that are not needed and will slow down the game you can delete everything in this folder except for one file and it is called "ccmerged" this file is required the rest can be deleted without any trouble.

The folder should look like this after you are done.


(IF YOU INTEND TO UPLOAD SIMS/LOTS WITH CC TO THE EXCHANGE OR ANY OTHER SITE DO NOT DELETE THESE FILES OR THE SIM/LOTS WILL USE NON CC FILES WHEN EXPORTED!)

Step 9 - Regul Save Cleaner (Essential)

Regal Save Cleaner can help keep old and new saves from getting too bloated with data which can lead to the dreaded "error code: 12 and 16" error while trying to save or even worse... save game corruption!

Bonus Step - In Game Options (Optional)

The game has some options that are on by default that can slow down the game if turned on. You may turn the off if you like.

Graphics Options (1st tab - Monitor) (Optional)

Turning the Refresh rate of the game to default setting is the best setting to go for since we have made the graphics card handle the refresh rate in the graphics cards control panel and with The Sims 3 engine the game has to be run at 60fps or under or the game physics engine will start to break resulting stuttering and broken physics.

⠀

General Options (3rd tab - Gears) (Essential)

Turning the options that I have circled in red to off will help the games performance greatly.

• Shop Mode option - if you followed the step earlier about restricting the ".jpegs" from generating then the shop mode is useless and can be turned off for a lot of extra performance.
  
  
• Interactive loading Screens Option - This was a good concept but the final product can actually make loading up your game even longer so disabling this option can make the game load your save file quicker.
  
  
• Disable Memories - This feature is really good for story telling and legacy save files but it can become very laggy with every sim in town getting constant memories all the time setting this to off will help the games performance greatly. If you like this feature turned on but still want performance I would recommend looking at the mod No (or fewer) automatic memories[modthesims.info] this mod makes it so only important events in your sims life is saved and not useless ones.
  ⠀
  ⠀
  

  Online/Social Options (7th tab - Antenna) (Essential)

  
  Turning off the options circled in red is highly recommend for performance since in game online stuff in the sims 3 was added poorly and results in a lot of lag on the games engine keeping the any online options off will improve performance greatly.
  
  ⠀
  

  Advanced Demographics Options (9th tab - Silhouette of Two Sims) - (OPTIONAL)

  
  Turning the options off that I have circled in red can improve performance greatly this just means that sims that are not any of these life states can not be turned into them, sims that are already that life state can not turn other sims into that life state. Do not worry sims that are already; say a vampire will not be turned to a human again if turning vampires off.
  
  
  
  
  
  

F.A.Q Section (Part 1)

Q: Does Sims 3 Work on Windows 11?

A: Yes! An older version of the OS had issues with 32bit programs but that has now since been fixed. If there are any problems with saving disabling the OneDrive app or uninstalling the OneDrive app should fix saving issues!

If you do not want to uninstall Onedrive or use Onedirve for other things refer to this video.

Q: Is there any way to make the game use more RAM?

A: No! The game is a 32bit program and there is no way to make it use more. Unfortunately no edits or magic can change this, its limit is 3.7gb at most no more than that unfortunately. The game is also already large address aware from the late night patch (1.17.60).

Q: My game is crashing but I don't know why!

A: The tool Sims 3 Crash Log Analyzer[modthesims.info] may be able to help, the tool reads your crash logs that the game generates when crashing and tries to narrow down the issue the crash logs for the tool to read are found at...

"Documents\Electronic Arts\The Sims 3"

Once at that location the files will be called "xcpt-(numbers).txt" let the tool read these files.

Q: I followed the guide but now my old save(s) file is having issues while playing!

A: Removing scripting mods from your game after the save is created will lead to the save files that relied on those removed mods to not function correctly or lead to save file corruption. This guide should be used with a fresh new save.

Q: After following all the steps my game does not launch after pressing play on the launcher.

A: The GraphicsCards.sgr & GraphicsRules.sgr may have not been edited correctly there will be backups made after using the graphics card tool in "Steam\steamapps\common\The Sims 3\Game\Bin" with "_old" at the end of them. Simply delete the edited versions then remove the "_old" from the backup files names and it will restore those files to vanilla.

Q: My GraphicsCards.sgr & GraphicsRules.sgr files are fine but the game still is not launching!

A: Check to see if your anti-virus software is not blocking the game due to smoothpatch by Lazyduchess, Since this script mod injects into the game it may be setting off a false flag and preventing the game from starting.

Q: The Mods folder is not being loaded in no matter what I try!

A: If you are using windows 11 and your PC user name has any Special Characters/Emoji's in it the game/mods folder will have issues loading up game files from the documents folder. This might be since the game can not read these types of characters in file path names.

Q: Why can't the downloads all just be in one big download?

A: A lot of the mods have an agreement section were you have to link to their sites to download and not redistribute. Respecting peoples work is the best thing to do for helping out the modding community for all their work. People put a lot if time into making mods so best to respect their wishes for their work!

Q: The mods did not take effect but I have installed them correctly!

A: Make sure to clear your games cache as some mod data stored in the games cache files. See more how to clean game cache in step 9! Also make sure that the mods folder has been placed into the games My Documents folder at "Documents\Electronic Arts\The Sims 3"!

Q: There are no sims in my town this also happens when I start a new save file!

A: Under Step 11 in the University life Mods Section there is a mod called "University Student Union / Library Shell Overrides" if the file from that mod called "UNI_FIX_MissingScienceProfessor.rar" is installed all pre-made sims will be deleted from new and old saves. Deleting the mod file "University - FIX Missing Science Professor.package" will fix sims being missing. DISCLAIMER! : Save files saved after having the mod installed can not be reverted!

Q: Why are the world fixes not included into this guide?

A: Some of the world fixes have corrupted data, they have a lot of good routing fixes but worlds with ghosts sims, mummies and simbots in them seems to have corrupted data. This is due to the Create a World Tool Having a bug were saving a world with ghosts, mummies or simbots in it will corrupt those sims data which can lead to save game corruption/errors, and these worlds were fixed using the CAW tool. More info can be read HERE[cawtool.fandom.com] under "A Warning about Ghosts & Mummies" and A Warning about Pets.

Q: Why do my game settings reset every so often?

A: This happens when you update your graphics card drivers and the game resets the graphics settings to the default lowest settings. EA never fixed this bug before moving onto The Sims 4. To get around this issue making a copy of the "Options.ini" file from "Documents\Electronic Arts\The Sims 3" and replacing the original with the copied version every you update your graphics drivers should get around the issue.

Q: How do I know if my graphics card has been successfully detected by the game after using the graphics card tool?

A: To know if you graphics card has been added successfully go to "Documents\Electronic Arts\The Sims 3" and find a file called "deviceconfig.log" open it, there should be a line that looks like this...

• Name (database) "your graphics card name here" [found: 1, matched: 1]

If it does not look like that but looks like any of these...

• Name (database) "your graphics card name here" [found: 0, matched: 1]
  
• Name (database) "your graphics card name here" [found: 1, matched: 0]
  
• Name (database) "your graphics card name here" [found: 0, matched: 0]

your card has not been detected and will need to be added. Also note the game will need to be launched at least once for "deviceconfig.log" to be present.

Note: If you have used Regal Save Cleaner the file will be deleted, launching the game again will re-generate the file! Intel 12th gen CPU and above users on the steam version of the game also may need the Alder Lake Patch to be installed so the game can run and generate the file.

Q: I'm getting an error that says "A Serious Error Occurred While Loading (Save File Name)"!

A: This is usually due to Onedrive interfering with the games save file location under the my documents folder. Disabling Onedrive or uninstalling Onedrive should fix this issue from occurring.

F.A.Q Section (Part 2)

Q: My game is still stuttering even after following the essential or all the steps!

A: Unfortunately The Sims 3 will still have some micro stuttering occasionally as the game makes calculations while playing things like...

• story progression.
  
• spawning and culling of sims to keep the world population under the maximum amount.
  
• Simulating sims moving around town.
  
• objects spawning.
  
• collectable spawning.

If its happening constantly the game may be running out of memory or the high detailed lot setting may be too high. It could also be that your graphics card was not detected correctly or smooth patch has not initialised correctly either. The stuttering can also be due to hardware or the world you are currently in as some worlds really put a strain on the games engine.

Q: How can I tell if smooth patch is working correctly?

A: To know if smooth patch is currently working you will need to locate Smooth patches settings file called ts3patch.txt it can be found at...

• Steam 1.67 - "Steam\steamapps\common\The Sims 3\Game\Bin"
  　
  
• EA App 1.69 - "EA Games\The Sims 3\Game\Bin"

Once there open the file "ts3patch.txt" and inside there will be a line called "Debug = 0" set the setting value "0" to "1" and save the file. Once running the game you will be greeted by a small window saying if smooth patch is running or not running.

Q: How do I Bypass the games launcher on Steam?

A: To bypass the launcher on steam first you need to...

• Step 1 - Find The Sims 3 in you steam library, right click on it and select "Properties".
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
  
• Step 2 - A new window will appear, under the general tab find the Advanced launch option settings section and put you games install location directing to TS3W.exe like this...
  
  

Use This Example For Default Installation Location

"C:\Program Files (x86)\Steam\steamapps\common\The Sims 3\Game\Bin\TS3W.exe" -%command%

Use This Example For Custom Installation Location

"Game\Bin\TS3W" -%command%

Note: This file path will be different depending on your steam install location or where the game is installed! If your edit town library is empty reverting these changes will fix this issue!

Another Way to bypass the launcher is to rename "TS3W.exe" to "Sims3LauncherW.exe". Just make sure to back up the original Sims3LauncherW.exe and TS3W.exe by moving them somewhere safe for later use.

The .exe files are locted at...
"Steam\SteamLibrary\steamapps\common\The Sims 3\Game\Bin"

• 06/11/2024 - Added the mod "Pigtails Glitch Fix" to "Step 11 - Bug Fixes | Base Game & Expansions" under Base Game section. The latest version is no longer a core mod and is now a scripting mod so it is now compatible with other core mods such as simler90's core mod.

  2025

  
  
• 01/01/2025 - Added a disclaimer to the mod "Realistic Fish Mod" Under "Step 11 Under Base Game Compatible Mods Part 1". Added some new information to the FAQ section.
  
  
• 14/01/2025 - Updated the title of "Intel Alder Lake Patch" Under Step 2 as EA recently updated the EA app version of The Sims 3 (1.69) to already include a fix for newer intel CPU's preventing the game from starting up, steam (1.67) users still require the patch however.
  
  
• 24/01/2025 - Added throughout the guide on how to get .ASI mods working on Linux / Steam Deck installs of the game.

• 27/02/2025 - Added the mod "Chance To Learn Teen Hangout" to "Step 11 - Bug Fixes | Base Game & Expansions" under Base Game section.
  
  
• 27/02/2025 - Removed the mod "Realistic Fish Mod" from Base Game section as it was causing infinite loading screens for some users when trying to load into Bridgeport and game crashes when trying to place the object "wall installed digital fishiness display" from the late night expansion pack. Its recommended to remove that mod for now until the problem is resolved.
  
  
• 07/03/2025 - Removed the step "Stopping Store Generated Jpgs (Optional)" as some users were reporting that it would lead to their game not closing on exit and being stuck open needing to be forced stopped by task manager. Using the game in smooth patch border-less window mode can get around this issue in most cases but the step has been removed. To revert these changes simply delete the blank "FeaturedItems" File that was made and the original folder will be regenerated on game startup.
  
  The file can be found at "Documents\Electronic Arts\The Sims 3"
  
  
• 15/03/2025 - Re-added the mod "Realistic Fish Mod" to "Step 11 - Bug Fixes | Base Game & Expansions" under Base Game section. Crashing issues with mod have now been fixed in the latest version. Monopatcher is now required for the mod to function.

Removed Steam deck setup information as it now has its own guide on how to setup and install mods on the steam deck.
  
  
• 17/04/2025 - Removed the section "Vanilla vs Fixed Comparison" as it was comparing from a very old version of this guide.
  
  
• 29/06/2025 - Added the mod "No More Non-Cases for Investigators" to "Step 11 - Bug Fixes | Base Game & Expansions" under Ambitions section. Added a disclaimer to the Realistic Fish Mod about which link to download the mod from on the mods page.

[N*rd]

I found the issue - it is outlined in here.
The reason seems to be OneDrive - as it forbids modifying an file that is uploaded.
So If anyone got Error16 - Stop/Pause OneDrive before booting up the game.
Go to "SaveAs" for the time beeing if the error still pops.

@Anime_Boom thank you for your assistance

[Anime_Boom]

@N*rd - Usually error 16 I think is to do with a save error I know code 12 is low game memory space while saving, 16 usually is to do with space on ssd/hdd. Is one drive installed? it interferes with the game, disabling it or removing it should hopefully fix saving issues or any loading issues.

[excelatrate]

@Spikey not just to play the game, these mods improve the game in many ways the vanilla experience was never able to achieve.

[SpikeyPeach]

sighs...great...more mods just to play the game. THANK YOU for the guide :) <3

[Anime_Boom]

@IntincrMars - Thanks! Added the mod to the list!

[IntincrMars]

I think this mod should also be on the list! Really helpful if you wanna experience the Ambitions investigator career https://modthesims.info/d/691682/no-more-non-cases-for-investigators.html

[lhw]

after i Step 10 and isntalld "all the mods" Brigeport wold not load XD
keept it to essecials for now. still thx this guid helps keeping the game from dying "literly" ^^

[Anime_Boom]

@Qazd - This should be fixed in the latest version if you are using the latest version of the realistic fish mod. Mono patcher is also needed for the mod to function correctly.

[Qazd]

When I tried to open Bridgeport it would get stuck at around 40%, and never progress even after minutes have passed.

After some trial and error, I found it was caused by the realistic fish mod, and the town loaded fine after I removed it. (Not a huge bother to me anyways)

Anyone else had this issue?

[Sammy]

@Krorounet I have both installed, both are great, stops the sp from generating new households. I prefer it as well the game does a good job at populating the town. It doesn't stop npc's being generated for npc roles though.
