The Sims 4 was originally released over a decade ago. While many would expect it not to have many issues, such as crashes, lag, and frame drops, that is not the case. The developers have had plenty of time with the game, and every update features an array of bug fixes, but new content is regularly being added into the game, and it can be overwhelming and cause several issues.

Memory boost is a feature available for The Sims 4 on PC. According to The Sims Team, memory boost is currently in early access, which means the developers are still actively working on it, analyzing player feedback, and improving it. However, players can enable it and give it a try if they please.

The Sims 4 players often experience game crashes, lag, glitches, and other errors - especially if they're playing with mods, a lot of custom content, or using an older, larger save file. The memory boost feature optimizes memory usage in The Sims 4 in order to prevent the aforementioned problems. Therefore, if players enable memory boost in their game, they should notice improved frame rates, reduced lag, and fewer game crashes.

To change memory boost settings in The Sims 4, players have to open the Pause menu, select Game Options, and then enter the Other tab. Here, they will notice a Memory Boost (Early Access) option, which will be set to Automatic as a default. Gamers can select Disable if they don't want to use the memory boost feature, and they can select Enable if they want to activate it.

Players must restart The Sims 4 for changes to take effect.

Once memory boost is enabled, separate save files will be created and tagged accordingly, so players can easily return to their initial, pre-memory boost save if they regret their decision or stumble upon some sort of error.
