@GraceyManor So you have 8 GB RAM, which means 80% of that is 6.4 GB. If the average amount The Sims 3 uses is between 1.7 GB and 2.8 GB, that means it alone is using 20-30% of your RAM (which is very normal for TS3, in my experience). If you take away TS3's RAM usage, the rest of the processes are using 40-50% of your RAM. Those numbers add up, even though they seem small.
I feel like 8 GB of RAM has to be properly rationed a bit more here. Razer Game Booster is helping because one of its functions is to free up unnecessary RAM usage. If Razer Game Booster helps, then that's great. But I'd still try to play without Google Chrome open because internet browsers just gobble up memory and aren't necessary. Heck, I have double the RAM you do and still close everything I'm not using (or isn't a necessary background task) when playing The Sims 3. If you need to use your internet browser, chances are you have a tiny computer sitting next to you that you can utilized instead. :3 (your cellphone lol).
The other option is to buy another stick of RAM, but since that costs money, it's more of an if-all-else-fails measure.
