Update 2:
- Improved FPS Limiter accuracy.
- Package installer/uninstaller no longer goes fullscreen borderless.
- The package installer/uninstaller will now be limited to 60 FPS regardless of your FPS limiter setting, as it can normally get into the thousands and it doesn't make much sense.
- Origin: Installing or uninstalling CC via the launcher no longer makes the patch not take effect once you launch the game.

Update 1: Added Borderless and FPS Limiting options.

This mod is not an all in one solution for lag; Essential improvements like NRaas mods, Graphics Rules and 4GB patching your game are still recommended, and your mileage may vary depending on your system. Some people don’t see much change, others see a huge improvement.

This mod alters the speed at which the game's processing threads run, which improves the overall performance of the game and some loading times. Most noticeably in Create A Sim, Create A Style and Buy/Build.

If you have a Retail or Steam version of The Sims 3, download the "" file and extract it into your Sims 3/Game/Bin directory.

For Origin users, download "" and extract it into your Sims 3/Game/Bin, and whenever you wish to play with the patch launch the game from the new "TS3PatchLauncher.exe".

Setting up/Tuning
The "TS3Patch.txt" file contains the configuration of the mod, along with some comments on what each option does.

The most important setting is the "TPS = 500" line. 500 is what works best for most people, the higher this value is the smoother the game will be, until the maximum value of 1000. Don't be afraid to play around with this number, 1000 works great for a lot of people (Although, as we are working with milliseconds, accuracy is not perfect, and between 500 and 1000 there are no in-betweens. Same applies to the FPS Limiter.)

The "Borderless = 0" line can be set to 1 if you want your game to run in Borderless mode if it's set to run windowed.

The "FPSLimit = 0" line can be adjusted if you wish to cap your FPS. It's always better to use your GPU control panel for this though if it's an option.

The "Debug = 0" line can be set to 1 if you want a message to pop-up when you launch the game, to make sure the patch is working.

Finally, the "Delay = 0" value can be increased in intervals of 1000 or 5000 if the patch is failing to apply. This shouldn't be necessary however, but the option is there in case it still doesn't work.

This mod might get detected as a virus, as it modifies the game's executable memory at runtime in order to modify a hardcoded function. This means some antivirus software, including Windows Defender, might remove it or prevent it from running correctly. If this happens you should add an exception to your Sims 3/Game/Bin folder.
Source Code for the mod is available below, so anyone can verify it does not contain malicious code.
If you get errors, try downloading the latest version of VCRedist. If you're running a x64 OS, download both the x86 and x64 versions.
If the patch doesn't work try increasing the Delay to about 1000-5000 in TS3Patch.txt

Known issues:
Buy Mode furniture previews will spin quicker the higher your TPS is. This is an EAxis coding mistake.
