Versions obtained through other means of sailing the high seas are not supported at all! Edit at your own risk if using game version 1.70. This guide is intended to be used with game version 1.67 Steam and 1.69 EA App on Windows 10 OS and Windows 11 OS, this guide was not made to be used with the game version 1.70 (64 bit Mac Update). If you have any questions feel free to look at the F.A.Q Section for common questions that have been answered or ask in the comments below and I will be sure to assist in any way that I can! If a step has an ' (Optional)' tag in the title means its up to you if you would like to add the tweaks to your game, If it has a ' (Essential)' Tag in the title it is recommended that you use the step to get the best results with the game and its performance. Every step that I have listed are the steps I personally use to make my game run much more smoother on my PC system. Welcome to my guide for The Sims 3 and how to improve its performance on newer PC systems.
