Re: Sims 4 laggy :((

@lindhard1234  Do you always play with the laptop plugged in?  Performance will be worse, often much worse, on battery, regardless of the other steps you take.

There's also a known issue with low fps when entering build mode, and that's not usually fixable.  But a workaround is to open and close the menu (the three dots in the upper right corner of the screen); let me know whether this helps.

Otherwise, please try playing in a clean user folder, just for comparison's sake.  Move the entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content.  Don't add anything to it yet; just see whether a new save runs better.  The point is not to abandon your current saves, only to try to figure out whether the issue is more about your system or the content you use in-game.

@lindhard1234 are you using Vsync? that can also limit your fps to the monitors refresh rate that may cause low fps 

@lindhard1234  Are you using any mods or cc?

@lindhard1234  Okay, just to reiterate, a new save in a completely clean Sims 4 folder—no mods or custom content added, no saves or other files from your old folder—still runs poorly even with the laptop plugged in?  Does it help to play while your laptop is offline, as in, no internet connection at all?  You can sign into Origin and put it in offline mode, then disable wifi before pressing Play.

If that doesn't help, I'd like to see the results of some hardware monitoring; let me know if you're interested.  You'd only need to run a (free) app while you played, then upload the results.

@lindhard1234  I'd like to see how your hardware is handling Sims 4.  Please download hwinfo from here:

https://www.hwinfo.com/download/

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 button for hwinfo, not lansweeper.)  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, open Origin, put it in offline mode, and take your computer offline.  Launch Sims 4 and play for at least 20 minutes, in fullscreen mode and on ultra settings.  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.

When testing, please again play a new save in a clean user folder.  Make sure you spend most of your time in live mode, not in CAS or Build/Buy, although you can test all three if you want.

First of all, i'm sorry for the late replay.

i hope i did it right.

when i first opened the game, it actuelly ran okay but then after just a short period of time it went downhill, and at last it didn't seem to be able to get above 20 fps. I barely spend any time in cas (chose a random soom from the bin), and i spend really short time in build/buy to place a pool (yes, i tried to drown someone) but whenever i entered build/buy the fps dropped to 2-4 fps (i didn't get to see if it got up when staying i build, cause i only spend a few seconds in build), but most of my time was spend in live mode.

I have a similar problem since some time now. The game shows severe lag spikes at times, most prominently while using the build mode. Whenever I enter the build mode there are spikes of very awful lags. I discovered two things that help against those lag spikes:

a) save the game while in build mode. The lags are gone for me after that.

b) hit the Esc-Key on the keyboard (once to open the sub-menu and a second time to close it again). This - absurdly enough - gets rid of the lag spikes in build mode for me.

If you haven't already I'd recommend to try those solutions. I can't remember though if they work in live mode as well - the spikes aren't as bad in live mode for me.

Between the first time I realized the lag spikes and the day I tried the Esc-key solution I factory-reset the game twice, made a full clean reinstall once (during which I removed every sims-related folder and file on my computer that I could find), updated my windows and my graphics card and run the game with a new save and without any mods, all because of another bug I had (the now fixed broken social profile bug) . None of that fixed the lag spikes though. I still have them. I run the game on an AMD Card (for many years now), on a desktop computer.

Of course those solutions are just workarounds. They don't solve the reason why the spikes are happening in the first place.

@Naodyr Unfortunately I don’t feel like these tips works for me ☹️( and my lag is also quite bad in live mode and not just build. But thank you
