8gb or 16gb ram?

@Vytautem  Adding another 8 GB RAM for 40€ would be an excellent investment overall, whether it helps Sims 4 a lot or a little.  It would certainly help with multitasking, both while you're playing and not, because swapping data from RAM to the page file (where the overflow data goes when it doesn't fit in RAM) is much slower than leaving everything in RAM.

Additionally, if your laptop does NOT have a dedicated graphics card, and I don't know whether it does based only on the model, 8 GB is only barely sufficient for Sims 4.  An integrated graphics chip borrows from RAM to do its graphics processing, as opposed to a dedicated card that has its own memory.  So that 8 GB installed RAM can become 6 GB very quickly, with 2-3 GB taken by Windows as well.

Regardless, if this is a cheap and feasible upgrade for you, it's absolutely a great idea and will make the laptop run better and for longer.

My Sims 4 steadily occupy around 15G of my RAM, but I have the “Ultra High” setting, and I build large house within thousands of objects.

Recently upgraded to 16gb ram but is it normal that I haven’t noticed any difference? My game is the same as it was and my laptop is still very loud and becomes very hot. It shows that I still have 13gb available.

@Vytautem  Having more RAM has at best a minimal effect on hardware temperatures; that's not why it can help.  Almost all the heat a computer generates comes from the graphics card, if the system has a discrete GPU, and from the processor.  The CPU will have a slightly higher workload if it has to swap more data between the RAM and the page file, but that's marginal compared to the work of running a game like Sims 4.

Whether you'd see a difference in-game depends on what the limiting factor was and is when you play.  More RAM definitely helps in general; the question is whether it helps in this specific situation.  If you'd like to investigate further, please post a dxdiag.

When you say you have 13 GB available, do you mean storage?  That's entirely separate from RAM.

I meant there's 13GB available of RAM. At least that's what is shows in task manager. I hope I did everything right with dxdiag. I'm no computers person and can't figure out stuff myself.

@Vytautem  Your dxdiag (and yes, you did it exactly right) doesn't list any Sims 4 errors, but it does show that two components of Acer software are crashing: the user registration app and a user experience improvement program.  I would suggest disabling both of those, which you may be able to do in the Task Manager's Startup section.  These programs could be using processing power, not just RAM, that you'd want available for Sims 4.

If you don't see these programs in the Startup list, please post a screenshot of that entire list so I can see whether one of them might be hiding under some other name, and also if there's anything else you don't need running.

Your dxdiag also lists a few generic Windows update errors, and it's best to clean those up.  So please run a couple of basic checks of your Windows system files:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes, and enter
• The system will start validating soon. If it throws an error, please list it here
• After it reaches 100%, hit Windows key-X again
• Again, choose “PowerShell (Administrator)” or “Windows Terminal (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes, and enter
• Post the message you receive here

Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates.  If any install, restart again afterwards.

None of the components show up in task manager but the user experience improvement shows up in regular search.
