@Mango_Habanero18 We have to start our analysis somewhere. We are trying to do long distance diagnoses and knowing your hardware could point to an issue. I'm not telling you anything at this point. Many issues can be traced to out for date drivers or improperly configured hardware. I have been scratch building pcs since the IBM pc was released and have been a computer gamer before Microsoft came to be so I think I have a slight advantage over the average user. The Sims games are very complex due to the addition of expansion packs and the fact the games are not linear in game play. The graphics system in your computer is complex and that being miss configured could affects the computer's performance. There are many things that can greatly affect the computers performance. I prefer to eliminate known hardware issues before pointing to the game. Because I am a user just like you I don't have access to the game code which means I can only go by what would normal game play be and if someone else is having the same issue and the fact that users can add cc/mods could also be an issue. My TS3 and TS4 I have noticed some minor bugs but nothing that breaks game play. My games do not lag and I can only remember one time TS3 crashed and that was before I put a power conditioner on my house. While we would like to help you with your lagging issue, lagging can be caused by many different reasons with many different systems and to describe what would happen with the infinite combinations of hardware would take considerable time. There are college level courses and A+ certification classes available if you REALLY want to learn about your computer. Originally there was the Disk Operating System which evolved into an operating environment. Your computer is a very complex appliance. Today's computer games have very complex coding and I invoke the Sherlock Holmes approach to trouble shooting - when you have eliminated the impossible, whatever remains, however improbable, must be the truth
