Serious lag after last game update

@Half-rose  Please run a dxdiag and attach it to a post.

Uninstalling might help, but unless your internet is very fast and it's not any trouble to redownload the game, it's worth trying to address other potential issues first.

I actually re-installed the base game, launched it and it is still lagging. It is confusing me even more because everything else runs fine except sims 4

I did the Dxdiag, here is the file

I  noticing this too, when playing things are fine, then go into build mod and starts to lag a little, then click back to live mods, the lag carries over . game play lags up to 30 sec before clearing. it even lag when you click fast forward 3

I have this exact same issue. 

Before I'd think I was one of the "lucky" few. But it seems that ever since this update more and more players are experiencing the same problem. 

I've had this problem before this patch though.. 

Fully re-installed the game with all packs, still lag, even with graphics settings changes. I re-ran Dxdiag again and it seems to have given a slightly different result pointing more errors.

 I just don't quite know what to do about them and I haven't found anyone that have solved their issue at this current time.

I don't know, at this point I'm just considering going into acceptance mode and giving up on playing this game again until one day It gets fixed.

@Half-rose  The Sims 4 errors in your dxdiag are likely related to the driver for your graphics card.  Since you already have the newest driver, please do a clean uninstall and reinstall.  Download Display Driver Uninstaller from here:

You can get the newest driver for your Nvidia card here:

https://www.nvidia.com/Download/driverResults.aspx/159887/en-us

Next, take your computer completely offline—disable wifi and/or pull the ethernet cord—and double-click the DDU.exe.  Take note of where the file will land, and click Extract.  If it's easier, you can copy the path and then paste it into the address bar in a File Explorer window.  Open the folder and then launch Display Driver Uninstaller.exe, and you'll get a message that you're not in Safe Mode.  Click OK, then go to Options and enable Safe Mode dialog.  Here's a screenshot of what your options should look like; make sure the box in red is checked:

Close options, and the DDU, and then open the DDU.exe again.  For launch options, choose "Safe Mode (Recommended)," and then click Reboot to Safe Mode (you'll need your password, so find it before rebooting).  Once you login, you'll see this:

In the blue box, choose GPU, then Nvidia if it's not already showing.  Then click Clean and Restart (red box).

Once your computer has rebooted, now back in normal mode, run the driver install .exe in custom mode.  Select "perform a clean installation" and install ONLY the GPU driver and the PHYSX software.

Reboot again, go back online, and see whether the game works normally.  If not, let me know.

@puzzlezaddict  Done

quick question before doing it. I never put any password on my windows. does that mean the safemode also doesn't have one or it comes with a pre-made password?

@LadyDarkSorrow  Try disabling your iCUE software while you play.  It's crashing pretty often and could be interfering with the game.

Your dxdiag also lists a couple of update failures, although those could have installed later.  Please run any pending updates manually: hit Windows key-i, choose Update & Security, and click the button to check for updates.
