Another optimization option will be available soon.
The authors of The Sims 4 have released a development diary dedicated to the new feature. It will appear in the game in an "early access" format.
Maxis talked about the "Memory Optimization" feature, which will be available in the settings menu under the "Other" tab.
This feature improves game performance by optimizing memory usage, reducing delays, increasing frame rates, and preventing memory-related crashes.
The ability to optimize memory in The Sims 4 will be available on September 23.
