Sims 4 mouse is very jerky?

Since yesterday I'm playing Sims again

have a slightly older Sony laptop with Windows 10 … Yesterday everything was quite ok but since today the mouse jerky and somehow lies so totally. What can I do? I've just turned up the pointer speed

The Mausruckeln will probably be more on the hardware than the mouse. So lags in the game because the hardware of your old laptop is not enough for a fluent gameplay of Sims 4. Alternatively, empty the memory

What else can I do about it? Will later sort out something

You could search the Internet for a few cleanup programs like CCleaner and especially for programs that speed up your PC, but I do not think it will do much. Otherwise, try to update all your drivers. After all that, reboot the PC. You can't do much more. Would you have a desktop PC now, I would advise you to renew a few parts but the laptop is nothing.
