@kaglett Sims 3 will stutter some no matter what you do. I have a desktop with an i7-9700K and an RTX 2070, and I get stutter when horses are on-screen or close by, and occasionally for no known reason. It's not ideal but also not terrible in the grand scheme of things, at least not for me. If you haven't already, try turning down water and high-detail lots in the graphics options; I use "mirrors only" and 2, respectively, when I'm not taking screenshots.
Other than that, the Smooth Patch may help, as will playing at your laptop screen's native resolution (1920x1080 in your case) if you're not already. If you do add the Smooth Patch, keep in mind that the .package files, the ones supposed to go into Mods > Packages, are not compatible with NRaas MasterController. These can simply be deleted; the files that go into Bin are fine.
Beware of performance improvement guides, which often recommend changes that won't help and could hurt performance. For example, many will claim that you can increase the game's RAM use. This is mathematically impossible, and the value that supposedly controls it refers to a different resource and is also 20 GB, not 2. The point is, read critically and make one change at a time so you can undo anything that turns out to be a problem.
For Control, I don't know anything useful about troubleshooting it. But I do seem to remember that you can play using DX11 or DX12, so try switching from whichever one you're using now to the other. Aside from that, you're better off asking on a dedicated forum for that game. And also, lowering your computer's baseline memory use may help a lot; see below.
Your second screenshot shows half the RAM in use at the time, which is a lot if you're not running anything in particular. Even 30% is a bit high for 12 GB installed. The third screenshot shows a number of apps that use significant resources and absolutely do not need to be starting with Windows: Adobe Acrobat, the Epic launcher, Java Update Scheduler, Lenovo Vantage, Teams. I would disable all of them at startup, and Grammarly too if you don't need it all the time. This doesn't mean the apps won't run when you want them to, only that they won't run on their own when you'd rather use that memory for something else.
