So I have no idea what @Jackomac43 is talking about and want to set the record straight for anyone coming here hoping for some solution to memory related crashes.
As @KiearaPhoenix has stated, to minimize how much memory the world uses, you simply need to de-bloat it in the ways she suggests. Also lower settings, remove unused content from your game, etc. There is no way in the files to edit the game's memory limit, lower or higher. And, frankly, lower would do nothing but make the game crash faster. It would reach a lower limit more quickly. If you could, theoretically, change the limit to 3.5 GB, that would just make the game crash at 3.2 GB instead of the 3.5-3.7 GB is crashes at now. lol
I can only assume the file Jack edited is Sims3.ini, which a lot of people misunderstand as it has a line that is:
MemoryUsageLimit = 20000000
The number you're reading there is actually 20 GB. And that is the default. But this is not related to RAM usage of the game, but instead related to the game's script heap, which is something you don't have to worry about. That number should be left as it is.
Simply put, The Sims 3 has the RAM limit of a 32-bit program and that's that. You cannot change this number in either direction and make any positive impact on your game. If you did change that value in Sims3.ini and you think your game is running better, trust me when I tell you this is a placebo effect.
Sincerely, someone with 21 GB of mods who has long mourned The Sims 3's 32-bit nature. :sweat_smile:
