Sims 4 Lagging After Update

@cherrylush

There are practically no reasons for this lagging
The only thing I can think of is that you have some programs, like Afterburner, Nahimic or in the background are running some open graphics program - or even Discord, Try to turn off all such programs, and Nahimic should be uninstalled at all
The graphics card works well. I just have to ask when you last cleaned the dust inside the computer. If the cooling system does not work well and the computer overheats, it can also cause problems.
Did you try to turn off the Internet when you were in the game?

The last option is to reinstall graphics drivers using DDU but I'm not sure if it will help you.
