In the newest update EA added these files to The Sims 4 on Windows:

  • TS4_x64_fpb.exe
  • Simulation_x64_fpb.dll

There are no in-game options to use this exe but you can force it by adding -fpb to the launch options. You can find them in game properties on EA app and Steam.

I haven't tested the performance. The only difference I noticed is that the "FPB" executable can't use DirectX 9. The option either disappears or is greyed out, with a tooltip that says "DirectX 9 is not supported in Memory Boost mode. To access this option, deactivate Memory Boost."

As far as I know this is the only mention of "memory boost" in game but I might've missed a text line.
