3booter + FPS Limiter
J. M. Pescado at More Awesome Than You has created a useful tool called 3booter which helps the game to start up and works perfectly together with FPS Limiter.

Both these tools have to be placed in the game's folder (C:\Program Files\Electronic Arts\The Sims 3\Game\Bin) and can be downloaded at MATY.


 * Download 3booter: http://www.moreawesomethanyou.com/ts3/tools/3booter-win.zip
 * Download FPS Limiter: http://www.moreawesomethanyou.com/ts3/tools/fpslimit.zip

Delete files in DCBackup
Go to Documents\Electronic Arts\The Sims 3 and open the DCBackup folder. There should be a file there called ccmerged.package: keep it(!) and delete any other file that may be in that folder.

Delete cache files
In order to prevent errors, it's highly advised to delete the cache files in Documents\Electronic Arts\The Sims 3, which are:


 * CasPartCache.package 
 * compositorCache.package 
 * scriptCache.package 
 * simCompositorCache.package </tt>
 * socialCache.package </tt>

The game will regenerate these each time it loads up so the player should always delete these files before playing.

WorldCaches (Windows only!)
'' Windows users only! Don't do this if you're playing on a Mac. ''

You can safely delete this folder. Don't worry if you don't have it: some players don't, while others do. Like the previous cache files, this one will also regenerate each time you load up the game.

Edit GraphicsRules.sgr
This can make the game run smoother and the in-game clothes changing is also faster.

Go to C:\Program Files\Electronic Arts\The Sims 3\Game\Bin</tt>, right-click on GraphicsRules.sgr</tt> and open it with Notepad. There should be four lines that look like this:

seti cpuLevelUber 4

seti cpuLevelHigh 3

seti cpuLevelMedium 2

seti cpuLevelLow 1

Change them to:

seti cpuLevelUber 4

seti cpuLevelHigh 3

seti cpuLevelMedium 3

seti cpuLevelLow 3

Combine your package files
If you use lots of mods, you can combine them all in a single package. This helps in decreasing load times.

Simply follow this tutorial. You will need S3PE, a free tool which can be downloaded here.

Reduce save game file sizes
Save game files can grow in size at an alarming rate, especially if you have memories enabled in your game. Large file sizes can drastically increase loading and saving times. To counter this issue, you can start by disabling memories in-game.

Once that is done, you can delete the "SNAP" and "_IMG" resources from your saved game files to reduce the size of your saved games. Follow this guide to remove them.

Installing NRass's mods
NRass has developed a number of mods that can help improve game performance, as well as fix several in-game issues. The most important mods include:


 * Overwatch, a mod that runs in the background and fixes a large number of issues, including performing a nightly cleanup of any vehicles, televisions, and stereos in the world to improve game performance and prevent possible problems from cropping up.
 * ErrorTrap, a core mod that also runs in the background and corrects any in-game errors that occur.
