EA is making a few changes in The Sims 4 with patch version 1.13 (December 2015).
One of which is a 64-bit version of The Sims 4.
We have wanted a 64-bit version of The Sims 4 since the release of the base game.
And now it is on its way! With the patch version 1.13, released in December 2015 (most likely the patch for The Sims 4 Get Together)
Another is regarding Mods, Custom Content and Game updates.
What do you need to do to get the 64-bit version of The Sims 4?
Nothing, Origin will update your game automatically (if you turned this off, you will need to do this manually)
And Origin will choose the correct version for your system (64-bit or 32-bit).
If your system has less then 4gb RAM or you are running Windows Vista (or lower) the 32-bit version is recommended
What are the advantages of 64-bit version.
The game will run more stable. Can use more than 4gb of RAM when needed.
The Sims 4 doesn’t need more than 4gb RAM, most of the time. But when you are on a highly populated lot, it does come in handy and your game will be less likely to crash.
So yay for that!
The Mac version of The Sims 4 is only in 64-bit
For more explanaition of how it works or if you want to run the 32-bit version read the EA post here.
Mods and Game updates
The other change is for mods and custom content in your game, if you have any.
Mods and game updates don’t always go hand in hand.
Sometimes a mod did not work anymore after a game update. And it is always recommended to remove any game mods and custom content from your game before updating.
Once you have checked that all your mods work with the newest update, you can play with your mods again.
But since a lot of people forgot to remove their mods before updating, EA has made it easier for you.
With patch 1.13 all mods will be disabled automatically after the update.
This means your game will be mod free when you start it up again.
Why do they do this? Mostly to ensure the patch will go problem free.
Secondly this gives you an opportunity to check your mods before enabling them again.
