This fix has been tested with the Steam version of the game, but should work with any client’s version of the game. Unlike AC Brotherhood and Revelations, this game has a 2 part fix, so please follow the instructions thoroughly.

Note: I have not tested this fix with the standard, non-remastered version of AC3, so I cannot speak for how well this will work for that version.

Part #1

  • Launch AC3 Remastered through Steam or whatever client you are using to play.
  • Press ALT+TAB to return to the desktop.
  • Open the task manager using CTRL+SHIFT+ESC.
  • Head over to the “Details” tab.
  • Right click the executable, typically towards the top of the list if sorted alphabetically.
  • Click “set priority.”
  • Change the value from “Above normal” to “High.”

Part #2

  • Right click the executable.
  • Click “set affinity.”
  • Uncheck ALL Cores except Core 0.
  • Click “OK.”
  • Right click the executable again, and click “set affinity” once more.
  • Re-check ALL CPU Cores.
  • Click “OK.”
  • You should be able to close Task Manager, and ALT+TAB back into the game, but now with even smoother and more consistent performance!

Please note: This fix must be done every single time you launch the game!

Hopefully this guide has helped you solve any issues you are having with stuttering and/or low FPS in a game that has no right performing poorly.
