Game started lagging out of NOWHERE? No change at all, at my wits end...

Wow... I feel like I seriously need to name my firstborn after you! Throughout absolutely everything I've done, and it took me two seconds and my game is running good again! Thank you so so much!!! 🙂

I marked this post as solved, as for a couple of hours it was, but unfortunately the lag has started again. I have attached my DxDiag as a final resort, as I'm at a complete loss of what to do- again if anyone sees and helps I am so so grateful! When I switched over to high performance, booting the game it seemed to be perfect again and I thought it was finally solved, but now the following day I am playing and it's back to laggy ☹️ 

Hi, I have the same issue. Could you test something?

• when you start the game fresh (after rebooting your machine) does it lag right from the start or not? When does it start?
• when you experience the lag, if you click the options menu and close the menu again, does the lag stop?

I'm curious if this is similar to the problem I have...

Hi! 

So I did this, and when I first open the game on high settings, it is completely fine for a few minutes, but once I can hear the fans on my laptop start and the game gets "going", it starts to lag. The lag can range from really, really annoying to just an occasionally glitch. It's totally inconsistent, but the one fact is that the longer I play, the worst it gets. 

I find opening the options makes the game worst, rather than better. I can almost tell straight away that the game is going to be glitchy because the menus aren't as 'snappy'. 

Do you find that your game runs better in laptop mode? I find that mine does, however I'm really stubborn to play it this way as it takes such a hit to the lighting etc, and because it was running perfect before, I'm stubbornly trying to fix it still. 

Did yours run fine before and then just stop? 

@Lcgreen97  hello 🙂 I have a PC though, not a laptop. I've been playing 1 save game (I don't have a save per family) since 2019 and all was fine until just a few days ago I started experiencing a lag that starts randomly. Testing it a few days, I noticed it starts about an hour into gameplay (real time) and can be noticed when switching from living to build mode or back. It stops for me, however, if I open any popup window such as the options menu, the notifications wall, or such a thing. It starts again when changing neighborhoods, or switching live/build mode. I installed Backyard Stuff newly a few days ago, after that I noticed it. I'm not sure if it's this pack, the recent update there was for the game, or something else entirely. It's so annoying really. ☹️

Okay, so although our issue is different, because of the 'randomness' of it, and the inconsistency of it, I have a feeling that once my game starts becoming demanding, windows is doing something in the background to limit the programme. I have played around with the DPI settings, by looking under the compatibility tab on the properties for the game, and I have made a small improvement. However, I don't really know what I'm doing and just changed something around- if anyone has any more specific advice on this, it would be super helpful. I'm going to keep trying to find a solution, and if I ever find one, I will let you know! 

Have you tried reverting an earlier version, temporarily disabling backyard stuff, and seeing if that's definitely the problem? In that case, you could maybe be eligible for a refund but I'm not totally sure. This isn't the case for mine, as I had no change between my game running flawlessly to laggy, which is why I'm so confused- no new packs or patch updates!

@Lcgreen97  Your new dxdiag shows a few errors from µTorrent, so please shut down any BitTorrent-related processes before launching the game.  (Go through the Task Manager's background processes list to make sure you've caught everything.)  If that doesn't help, please try playing while your computer is offline again, now that you've set high-performance mode.

If you still get lag, please do some hardware monitoring.  Download hwinfo from here:

You don't need to install anything if you don't want to; just choose the Portable version, unzip it, and launch it from Downloads or wherever you want.  (If you would like to install, be sure to click the green button, not the orange one.)  Because you have a Mac, you may need to apply a fix to get hwinfo to work:

Restart your computer, and don't open any other apps.  Launch hwinfo, choose "sensors only," and click the icon that's a sheet of paper with a + sign to start logging.  Save the file to your desktop for easy access later.

Wait five minutes, then launch Sims 3 and play for 20 minutes or until it crashes.  Click the same button to end logging.  Then upload the log to a third-party free filehosting site and link it here.  Please leave it in .csv format, or if you use OneDrive to share, please compress it in .zip format instead.
