The Sims 3 Performance & Bug Fix Guide 2022
By Anime_Boom
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.

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 or ask in the comments below and I will be sure to assist in any way that I can!

Happy Simming!!

This guide is intended to be used with game version 1.67 and 1.69 on Windows 10 OS, this guide was not made to be used with the game version 1.70 (64 bit Mac Update) or Windows 11 OS since it has some unsolvable issues with saving and loading save games. Edit at your own risk if using game version 1.70. Linux users should have no issues.

Getting Started!
To get started on this guide you will need basic knowledge on how to install The Sims 3 mods if you are new please refer to this Site below on how to set up a "Mods" Folder for The Sims 3.

Mod The Sims - Setting up a "Mods" Folder.[]


Origin/EA App (1.69) Users - You will need to install Lazy Duchess's Origin launcher for some of the types of mods such as ASI mods to work with that version you can download it HERE[] Make sure "Load ASI Mods" check box on the launcher is checked and run the game with this launcher!
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...
  • GeForce 700 Series
  • GeForce 800 Series
  • GeForce 900 Series
  • GeForce 1000 Series
  • RTX 2000 Series
  • RTX 3000 Series
  • GTX Titan Series
You will need to use the tool!

Step 3 - Nraas Mods (Essential)
Nraas mods will help your game run smoother and less likely to crash, some other nraas mods can improve game-play and add more to the game.

This part is in two parts Nraas Mods that fix the game and Nraas Mods that enhance the game,

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[] - Error trap prevents the game from crashing when the game hiccups on itself and will notify you in game when it has prevented a crash it also leaves crash logs so you can track down what was going to make your game crash (Download the Steam version).

Nraas Overwatch[] - 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 Tempest[] - Has an option to clean up all fallen leaves around the world after fall has ended. (Install only if you have seasons installed.)

Step by step guide with pictures to set up "Nraas Tempest" remove fallen leaves setting can be found HERE[]

Nraas Master Controller []- 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[] - 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 Systems Core Mod (Optional)
Simler90's Gameplay Systems Core Mod fixes a lot of issue and bugs with the base game and many of expansion packs, it even fixes the bug with the pie menu taking a few seconds to load after clicking on a sim or object in game!
However to get this mod to work better with Nraas mods that I have listed in this guide you will need to follow a few steps to get it working with those mods. Other Nraas mods that are not listed on this guide will or might have conflict problems!
Simler90's Gameplay Systems Core Mod Can be downloaded HERE[]!
Step 1 - Download Simler90's Gameplay Systems Core Mod and place it somewhere like the desktop for now.
Step 2 - Download S3PE a Sims 3 package editing tool (you can download the installer or the "Unpack-It-Yourself version"), Placing it anywhere you like does not matter of install location. Download S3PE HERE[] or on the mirror link if the first does not work HERE[]
Step 3 - Once S3PE is installed open up the program. After the program opens go to "File/Open"
Step 4 - Locate "simler90's Gameplay Systems Core Mod" and open it.
Step 5 - Once it has loaded up it will look something like this
Next Download one of these option files Depending on if you are or are not using Nraas Story Progression...
Only Choose One!
  • Non Nraas Story Progression Users - HERE![]

  • Nraas Story Progression Users - HERE![]

Once downloaded Click and Drag the file of choice onto the S3PE screen.
Step 6 - Once You have placed the file you will be greeted by this window, all you have to do here is press the "OK" button.
Step 7 - Once done it should look like this.
This means is was successful! Now saving the file is needed! Go to go to "File/Save" to save then exit the program.
Step 8 - Once its saved grabbed the mod and place it in the "PACKAGES" folder at "Documents\Electronic Arts\The Sims 3\mods\Packages" this is important! After it has been placed in the packages folder, place all your Nraas mods from the last step into the "OVERRIDES" Folder found at "Documents\Electronic Arts\The Sims 3\mods\Overrides"! This will make sure that Nraas mods will have higher priority when loaded for more compatibility between the mods!
Step 5 - Limiting FPS (Essential)
Limiting the game to only 60fps or 30fps will increase game performance dramatically. The reason this being is that the engine The Sims 3 runs on is optimised for 60fps and under so limiting the fps to 60 or under will improve the games overall performance.

Origin (1.69) users only need to apply this to the ts3.exe since origin do not use or have the TS3W.exe file!

If you do not see a frame limiter on your graphics control centre settings "Smooth Patch" from "Step 2" has a frame limiter built in that you can enable by editing "TS3Patch.txt" in the games directory were "Smooth Patch" was installed.

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

Step 2: When the control panel comes up click on the tab "Manage 3D settings"

Step 3: Then click the tab "program settings" and on the drop down window select The Sims 3's .exe file (ts3.exe and ts3w.exe)

Step 3.5: If the The Sims 3's .exe files are not in the drop down window click the "Add" button and locate them were you have the game installed and click "Add".

Step 4: In the little window scroll down until you find the option "vertical sync" turn this option to "ON" for both ts3.exe and ts3w.exe.

Step 5: Find the max frame-rate option in the same window and limit the game to use "60fps" in the drop down window for the option.
Step 6: Press "apply" at the bottom of the window for both of the .exe when applying the vsync setting and close the window after completion.

Step 6 - Disabling Game Preloader Settings (Optional)
With newer HDD and with SSD games no longer need to load things for the game into the PC's ram which in most cases when games does this it slows them down, disabling the settings that tells the game to do this will speed up the game.

This step is best for people who experience long load times, long stutters or just in general really slow unresponsive game. If you do not experience these after following the essential steps in this guide this step is not needed.


Step 1 - Find "Sims3.ini" in your games "bin" folder and open it with notepad by right clicking on it.

Step 2 - Once the file is open look for "[Preloader]" under it will be to options set to "true"
Step 3 - Set these two options to "false" it should look like this.
Step 4 - After the change press "Ctrl + S" to save or at the top of the program go to "File/Save" then close the program.
Step 7 - Making The Game Use More CPU (Essential)
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" in "SteamApps\common\The Sims 3\Game\Bin" and open it 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 8 - Making The Game Use The Correct Amount of Vram (Essential)
Step 1 - Locate "GraphicsRules.sgr" in "SteamApps\common\The Sims 3\Game\Bin" and open it 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" this number can be changed to"4096" (4gb) if you card has that amount of video memory or more. If the number is "32" it will need to be changed to "4096" (4gb) or "2048" (2gb) depending on how much video memory you have.

Step 4 - Save and exit the document.

Note - If you are on a Mac computer its best to leave the number if it is "32" to be safe.
Step 9 - Restricting Store Generated Jpgs (Essential)
With an update to The Sims 3 back in 2011 EA made it so you could browse the online store in game this feature surprisingly slows down the game a lot.

How it slows down your game is that it generates images of the store items everytime you click on the store feature in game then in a folder were the sims 3 stores all your save files the game generates hundred of jpeg files over and over again. Disabling this folder from updating will increase your games performance. The notorious folder is called "FeaturedItems".

~~!!You will need ADMIN rights to do this step!!~~

This is how you disable the "FeaturedItems" folder,

Step 1: Locate "The Sims 3" folder in your "My Documents" under "Electronic Arts",
\Documents\Electronic Arts\The Sims 3

Step 2: Once in "The Sims 3" Folder find the folder called "Featured Items" and right click on the folder and select properties.

Step 3: Once selecting properties a little window will apear once it has apeared click on the "Security" tab at the top of the little window.

Step 4: After clicking the tab you will see this window

Click on the Edit button to the centre right

Once clicked tick all the boxes in the rectangle below so that "Deny" is ticked for all options.

And then Click Apply and close the 'Featured Items" properties window.

Step 10 - 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.

Step 11 - Regul Save Cleaner By Onebeld (Essential)

When saving The Sims 3 will actually bloat the save files with unnecessary lines of code slowing down you game when loaded. The tool needs to be used EVERY-TIME YOU SAVE when exiting the game.

Regul Save Cleaner[] - This tool is really good for cleaning your saves you get to choose what you want cleaned up in your save file, shows you comparisons of before and after the clean and can even clear chache files for you in one click of a button! You can even select an option to make a backup when cleaned. All in one easy to use tool with nice UI! (It even has a dark/night mode theme for people who like to use dark/night mode UI's)

Consider Supporting Onebeld for making this awesome tool? You can HERE![]
Step 12 - Clearing Cache Files (Essential)
In "The Sims 3" folder under the folder "Electronic Arts" the game will generate chache files every time its starts up if never been deleted before the file size over time will become very large and will slow down the game.

The cache files that are safe to delete after every-time playing the game are...

- compositorCache.package
- CasPartCache.package
- scriptCache.package
- simCompositorCache.package
- socialCache.package

Deleting these files before running the game will make the game run smoother.

Regul Save Cleaner[] also includes an option to clear cache at a click of a button see the step above for more information!

Step 13 - Bug Fixes | Base Game & Expansions (Essential)

Store Content Bug Fixes
Only use these fixes if you have the store content installed from the official The Sims 3 Store
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[] 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.

Bonus Step - Making Sims Able To Walk Past Each Other At Realistic Distances (Optional)
In The Sims 3 sims love to tap their foot and huddle all at a doorway that could easily have more than one person going thought it at once, this tweak makes it so that sims move more like they do in The Sims 4 when navigating around each other and objects.

Step 1 - Locate "Sims3.ini" in "SteamApps\common\The Sims 3\Game\Bin" and open it in notepad (or notepadd ++ makes things easier to edit and find)

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

Step 3 - In the "Config" Catagory change ONLY "DynamicAvoidance_FieldRadius, DynamicAvoidance_InactiveFieldLength, DynamicAvoidance_MinNonIntersectingDistance, DynamicAvoidance_FieldLengthPad, DynamicAvoidance_StopDistanceMultiplier" all to "0.1"

So From This

To This

Step 4 - Save and close the .ini File.
Vanilla vs Fixed Comparison
In these comparison videos I recorded Vanilla with no mods except "Intel Alder Lake Patch[]" by Lazyduchess due the game being completely un-launchable without it on 12th gen CPU's which I have a 12th gen CPU and fully fixed with mods and settings.

BridgePort and Isla Paradiso (coming soonish) are the worlds I will be using in the comparisons below due to most players not being able to play in these worlds with vanilla settings and no mods.

My PC specs are during the recording of these comparisons...
  • RTX 3090 TI
  • 64 GB DDR5 RAM
  • i9-12900K, 3200 Mhz, 16 Core(s), 24 Logical Processor(s)
  • Game installed on a SSD

Loading Times For Bridgeport
The Vanilla game seems to have another minute of time on loading compared to the Modded and fixed version of the game.
  • Vanilla Loading Time

  • Fixed & Modded Loading Time

24 Hours In Game From a Fresh Save At Full Speed 3 Time Speed Bridgeport
    The vanilla game takes another minute and a half to get through a whole 24 hours in game compared to the fixed and modded version of the game.
  • Vanilla 24 Hours Speed 3 Time

  • Fixed & Modded 24 Hours Speed 3 Time

    • (The Sims seem to be in a worse mood this is due to a mood mod[] I have and no fridge shopping[] there was no food in the house)
F.A.Q Section
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: Why am I getting "Error Code: 16" all of a sudden even on new saves?
A: The latest Windows 11 update has major issues with 32bit programs and how they manage ram/memory usage. Sims 3 being a 32bit program now has a lot of issues on the latest Windows 11 update. A work around is to set the games "ts3.exe" in the games bin to run in windows 8 compatibility mode the ts3.exe is found in the folder here...

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

Thanks to @Acidlure on twitter for the potential work around for the issue!

Q: The EA App is saying The Sims 3 is already running when its not!
A: This is a known issue with the older version of Lazy duchess Origin Launcher it is now updated to work with the EA app with the latest version! Please make sure to update to the latest Lazy Duchess launcher version! Download the latest Version HERE![]

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 in "Steam\steamapps\common\The Sims 3\Game\Bin" with ".bak" at the end of them. Simply delete the edited versions then remove the ".bak" 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 and shader-framework by Lazyduchess, Since these scripting mods inject into the game it may be setting off a false flag and preventing the game from starting.

Q: My GraphicsCards.sgr & GraphicsRules.sgr files are fine but the game still is not launching! But I'm on Origin!
A: If on origin version of the game (1.69) please remember to be using the Launcher By Lazyduchess[] this is essential for origin users for ".asi" mods to function!

Q: I edited the MemCacheBudgetValue in GraphicsRules.sgr from an older version of this guide and now my game is borked how do I fix this?
A: Open up GraphicsRules.sgr with notepad or notepad++ and then press "Ctrl + F" and search for "MemCacheBudgetValue" once found revert the number value next to it to its vanilla amount which is "209715200" then save the file.

Q: I'm getting strange graphics glitches on my sims in game and in CAS!
A: Try removing shader tweaks and launch the game and see if the problem still persists, if it does something went wrong when editing GraphicsRules.sgr.

Q: My game seems to slow down/stutter around 3am to 5am in game time and I don't know why.
A: This stuttering or lag spike is due to how the game works. At 3 am to 5 am the game does all of these following things...
  • Spawners for rocks, gems, small animals, flowers, plant seeds, plants growing, fish spawners are spawning in or refreshing.
  • Festival lots on a new season will change over to the new seasonal themed decorations and objects this can cause the game to stop for a second or two.
  • Story progression (Vanilla) usually pushes changes around this time.
  • Nraas Overwatch cleans up your game around 3 am (Can be altered in game in the settings menu for the mod at town hall)

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[] at moreawesomethenyou under "Drawbacks".

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. There is now a workaround thanks to @acidlure on twitter found HERE

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.

    @Wolf - If you want to, personally i wouldn't just to play a game. Windows can be expensive so its up to you to decide.
    Wolf 36 minutes ago 
    So should I buy windows 10?
    Anime_Boom  [author] 1 hour ago 
    @Wolf - As i have said earlier it is most likely windows 11 it has way too may issues with sims 3 currently.
    Wolf 2 hours ago 
    Nope I don't have SpecialK and I have no clue what it is other than a cereal.
    FiftyTifty 2 hours ago 
    @Wolf If you're using SpecialK, make sure the game is running in windowed mode first.
    Wolf 4 hours ago 
    Now it's black screen on launch. And it never loads. That firewall thing did nothing. How do I fix this? Should I just buy windows 10 at this point? Do you think it will fix allot of the issues I am having or do you think It's to do with my Processor? Or a software issue?

    I ask anyone else on here to please help me. If it's working for the rest of you. I need help. I'm lost here.

    @MrShinobi I've run TS3 on an AMD Phenom II x4 965 + AMD HD 7850, intel i7 6700k + AMD HD 7850, intel i7 6700k + AMD Vega 56, and a Ryzen 9 5800X3D + AMD Vega 56. They all had the same microstutter, but framerates were fine.
    Anime_Boom  [author] 23 hours ago 
    @MrShinobi - My PC specs are listed in the "vanilla vs fixed comparison" section and thanks for testing after upgrading when you get to, it will hopefully make sure if its hardware dependant or not. :spyro:
    Anime_Boom  [author] 23 hours ago 
    @CardmanOfficial - Hello! :VBCOOL: I think the worlds on the origin/ea app store are tied to your thesims3 .com so when purchased they can be downloaded into your steam launcher by logging into you sims 3 website store account since the sims 3 store uses EA accounts could be wrong though. I bought the worlds using the sims 3 website and had to use my EA login and buy simpoints to use the store. :cozybethesda:

    As for logging in online while in game, the only benefits are achievement tracking for your sims 3 my page the rest slows the game down a lot... The in-game store browser I think does not function when disabling the features items folder from step 9, its better to use a web browser anyway since buying things in-game makes you open the launcher and restart your game anyway.

    Hmm it could be, I currently have i7-5820k and a GTX 1080 (not Ti). I am upgrading to either the RTX 4000 or the upcoming AMD 7900 XT next month, I will report then if it makes a big difference.
