I own a legit copy of the Sims 3 and have never owned a pirated version so I can’t say whether or not these settings will work with a pirated version of the game. All of these tips have been gathered from all over the internet and also some things I have picked up on my own over the years. I have applied all of these fixes in my own game and I still experience lag so this is by no means a guide to completely eliminate the lag in the game but a guide to perhaps help your game run a little bit smoother.
Some things may work well for others while some may not make a difference at all.
I made this guide a few years ago for another forum so I’m always open to new suggestions/edits etc. The Sims 3 can be tricky to get running correctly on modern computers so I figured I would share what I learned over the years. Still looking for that “Sims Fix” I found myself going back to playing The Sims 3. Lately I have found the direction of The Sims 4 to be rather lackluster.
