The Sims 3 | Performance & Bug Fix Guide 2020
作者: Anime_Boom
This is a guide on how to make The Sims 3 run smoother, use more ram and fix some bugs on newer systems.
Step 1 - Making The Game Recognize Newer GPU Models to fix UI/Game Lag
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 recognize newer models and believe it or not make you game run slower.

Making the game recognize newer GPU models will benifit in less lag spikes when using CREATE A SYLE/IN GAME UI and general GAMEPLAY performance since the game will use the newer cards benifits since its knows the cards model.

The Sims 3 by default can only recognize cards from gtx 600 series and under if you have any card(s) higher than the gtx 700 series you will need to use the The Sims 3 GPU Add-on Support TOOL to add your GPU to the games list of known GPU cards. (you will need to run the game at least once only need to get the the main menu then exit)

If you wish to edit your game files on your own proceed to the video provided below.


Step 2 - Nraas Mods
Nraas mods will help your game run smoother and less likely to crash

To Install Nraas you will need basic knowlegde 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.

Here are the nraas mods that are needed...

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 safley will also remove unsued 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.

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 Master Controller Integration[] - Makes it so that the "Create A Sim" settings you set under the setting section of master controller apply to the normal "Create A Sim" button example, "new game CAS" or Edit Town CAS". Using Compact hats, clothing, make-up ect will make CAS Load tremendously faster than it does without. (THIS MOD REQUIRES YOU TO HAVE MASTER CONTROLLER INSTALLED)

Story Progression[] - Makes the story progression more varied and interesting (I prefer the EA's Story Progression but if you want more going on in the town I highly advise to use this mod)

Step 3 - Limiting FPS (Only Fullscreen Mode)
Limiting the game to only 60fps will increase game performance dramatically. The reason this being is that the engine The Sims 3 runs on is optomized for 60fps and under so limiting the fps to 60 or under will improve the games overall performance.


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: 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 4 - Making The Game Use More RAM
The Sims 3 Is known for chugging along as it uses very little RAM by default but with this simple tweak you can push the game to use more of the RAM on your system.

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 "MemoryUsageLimit" and press enter.

Step 3 - There you will find that next to "MemoryUsageLimit" there will be the number "20000000" Change this number to "40000000"

Step 4 - Save the .ini file and close it.

Step 4.5 - Making The Game Use More CPU
Step 1 - Locate "GraphicsRules.srg" 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 "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 4.5b - Making The Game Use More Vram
Step 1 - Locate "GraphicsRules.srg" 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 "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 is currently set so the game only uses 2GB of vram if you have more replace it with you current amount on your installed graphics card. For example I replaced "2048" with the number "8079" since I have a 8GB card installed into my PC.

Step 3.1 - (skip if you know your GB size in your GPU) if you do not know how many gigs you have on your graphics card download the tool VRamSizeTest v1.0[] and use the "VRamSizeDX9.exe" in the downloaded archive it will tell you how much vram for DX9 games you can use.

Step 4 - Save and exit the document.
Step 5 - Making Sims Able To Walk Past Each Other At Realistic Distances
In The Sims 3 sims love to tap their foot and huddle all at a doorway that could easly have more than one person going throught it at once, this tweak makes it so that sims move more like they do in The Sims 4 when navagating 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.
Step 6 - Fixing Improperly Rendered Body Hair & Tatoos on Your Sims
For some reason EA made it so that at high settings or with a HQ mod installed sims with body hair or tatoos would have blurry mess on them instead of clear textures this tweak fixes that issue so you can see sims tattoos and body hair in all their non blurry glory!

Step 1 - Locate GraphicsRules.srg 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 "ShaderSkinCompositing" and press enter.

Step 3 - There will be four "ShaderSkinCompositing" some will be set to "True" by defualt replace these with "false" and save the file.

Step 7 - Removing The Horrid Bloom Effect (Optional)
The Sims 3 has the worst bloom effect imho ever and it can lag your game in some instances were there could be tons of light sources creating bloom, disabling this will also make the game not an eye sore to look and and more pleasing to the eye.

Step 1 - Go to Steam\SteamApps\common\The Sims 3\Game\Bin and open the file "GraphicsRules.srg" with Notepad (Or Notepad ++ its easier to edit and find things with)

Step 2 - Once open click "Ctrl+f" a seasrch bar will appear, type in "AdvancedRendering" and press search.

Step 3 - once located Copy the line "prop $ConfigGroup RenderPostProcessEnabled false"

Step 4 - Make a new line under the "on" setting and paste the "prop $ConfigGroup RenderPostProcessEnabled false" under the "prop $ConfigGroup RenderForceMinspecShaders 0" line

Step 8 - Restricting Store Generated Jpgs
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 neutorious 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 9 - Cleaning DCBackup Folder
When installing things through the launcher the path to those files are saved in this file but of corse 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 10 - Save Game Cleaning

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 EVERYTIME YOU SAVE when exiting the game.

To Clean your save games from bloating use the tool Save Cleaner By Kuree, V2.2 is the latest but sometimes can make in game camera photos go blank if this is the case try older versions and see if the problem persists. (If you are using steam version of the game use "For Version 1.67" If you are using Origins Version use "Version 1.69")

Save Cleaner V2.2 (For Version 1.69) - DOWNLOAD[]

Save Cleaner V2.1 - (For Version 1.69) - DOWNLOAD[]

Save Cleaner V1.1 - (For Version 1.67) - DOWNLOAD[]


(You will need to clean your save game every time you save and exit the game)
Step 11 - Clearing Cache Files
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 everytime 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.

Step 12 - The Sims 3 World Fixes (Only For New Saves!!)
This step is only for new saved games already saved games will crash/break when loading on start up if the new world files are installed on saved games that used the old world files.

When EA was making the worlds for The Sims 3 they missed a lot of bugs on the worlds terrain and path finding which ends up in sims getting stuck and lagging out the game.

Step 14 - (Optional) In Game Options
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)- Turning the Refresh rate of the game to default setting is actually in game vsync so turning it to this option will be a better option for the game because the games engine can have trouble if the FPS is higher than 60 which can cause stuttering and lag.

General Options (3rd tab - Gears) - 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 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) - Turning off the options circled in red is optional but highly recommend for performance.

Advanced Demographics Options (9th tab - Silhouette of Two Sims) - (OPTIONAL) turning the options off that I have circled in red can improve perfromance greatly this just means that sims that are not any of these life states can not be turned into them and 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 vampire off ect.

Step 15 - Enjoy A More Smooth Game Experience
Hopefully your game will now be a more smooth experience. :)

Happy Simming!

@THETA🌭ZER0 Aww thanks :2017meatball: i did some looking there is a mod that can disable social groups fully if can be found here - there are also options on the page to disable certain groups if you want some of them gone but some still there. Its recommended to only use one file at a time though and the mod can conflict with faster skill gain mods. :cozybethesda:
THETA🌭ZER0 12月3日 12時49分 
The only time I comment on guides is generally when I have some sort of criticism. This isn't the case, this is an incredible guide and you deserve any accolade you get for writing it.

Only thing I want to ask is I recall there being a mod which turned off the social group popups introduced in University. Do you know about such a thing?

Anime_Boom  [作成者] 11月30日 20時24分 
@WZG_missclick*MSI the world fixes must be used on a new save game only, pre-existing save files will not load if you have a save file made from the old world files when you have the world fixes installed

@Order_of_Dusk The site seems to be working fine for me maybe its a region thing or the severs were down at the time, Also sometimes it can take a while to get the verification email.
Anime_Boom  [作成者] 11月27日 21時23分 
@1960s Salesman that bug is actually pretty common used to get it with certain CC items a few years ago sometimes CC items just make the poses for save game icons go all strange. if you dont have any CC installed (hair clothing ect) its nothing to worry about its just a visual bug they never fixed it does show up more if you use CC how ever.
WZG_missclick*MSI 11月27日 18時56分 
Overall this tutorial is the best atm, but i dont know which part i fucked up on cuz i cant load my world now (it hangs on loading screen)

Hey not sure if this is just me but Naughty Sims Asylum seems to be broken, it doesn't send the registration email so might need to find other sources for anything from that site.
