Mods for overall performance and stability
[Please read: How to install mods]
Sims 3 has no built-in method to clean up errors and data corruption, and some features are prone to breaking or not properly limited by the game itself. Without any interventions, saves can become corrupted over time, leading to progressively worse glitches until the saves are unplayable or won’t load at all. These mods improve the game’s overall stability and help prevent or fix minor issues before they become major ones.
This list represents my own recommendations. All of the mods are compatible with patches 1.67 (disc/Steam/Mac 32-bit), 1.69 (Origin/Windows), and 1.70 (Mac 64-bit). Please read the documentation for each mod before installing.
NRaas ErrorTrap: This mod catches many errors before they can cause corruption. It’s also quite chatty, so don’t be surprised to receive related notifications. [This is a core mod, so be sure to download the version for your type of install (1.69/Origin, 1.67/Steam, or 1.67 other; 64-bit Mac players may use any of the options).]
NRaas Overwatch: This mod performs basic resets and checks for potential outstanding issues on its nightly cleanup run. It also flags and can reset stuck sims that would otherwise drag down game performance.
NRaas Traveler: This mod replaces the EA-made travel transition with one that’s much more stable and less prone to breaking. It’s recommended for anyone with an expansion that supports travel, so World Adventures, University Life, or Into the Future. It also greatly expands travel options for players with or without these packs; please see this FAQ for more information.
NRaas Register: This mod governs role sims, as in, those that staff a role-giving object plus a few others. It also has settings governing stray animals, which is especially useful in preventing problems with strays in towns not built to accommodate them.
NRaas Traffic: This mod governs the general use of vehicles and can prevent the overspawning of food or ice cream trucks or Showtime career performance limos. It’s especially recommended for saves in Starlight Shores or any world with a population of sims high up in the Showtime careers.
NRaas MasterController: This mod does nothing on its own but is a tool for issuing one-time commands. Its reset functions are useful for the ability to reset anything from a stuck sim or object to the entire town.
