New pack and latest update ruining the game

abyjo2003​  The drag issue was fixed with the day 0 patch released alongside EBN.  The pregnancy issues are on EA's radar and should be fixed sooner or later, hopefully sooner.  It's possible that mods that include pregnancy-related features won't be viable either until that point, since modders probably don't want to spend time reconfiguring their creations only for EA to change the underlying code yet again.  So you'll just need to wait for that process to play out.

For the performance issues, please describe them in more detail.  I don't know whether I can help with that, but I can certainly try.  If you're interested, please also provide a dxdiag.  Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.

The game is just running extremely slow. The mods are now fixed thank goodness due to EA's latest patch fix, but the game itself is still very laggy and unresponsive to commands. I have attached the file you have asked for, hope you can help. Thankyou :)

abyjo2003​  Your computer's page file is somewhat large, but it's almost completely used.  The page file is where the processor stores data that would normally be in RAM but doesn't fit, so this could explain why Sims 4 is running so poorly.

Since your computer's system drive has plenty of free space, you can simply increase the size of the page file.  But given how much is in use, I would instead suggest trying to cut down on the number of background processes running.  Open the Task Manager, click the Startup icon, and disable anything that doesn't need to be running all the time.  For example, you might see Edge or Teams on the list.  Disabling these doesn't prevent them from working; it just means they won't start with Windows and keep running.

If you're not sure what you're looking at, feel free to post a screenshot or two.

When you're done, restart your computer, wait two minutes without doing anything, then open the Task Manager (but nothing else yet) and let me know how much RAM is in use overall.  It'll show as a percentage in the Memory header.  Once you have that number, see how Sims 4 runs.

Okay thank-you so much, will try that soon.
