As you might already realize this is not optional. Besides being horrible for game performance, those frame rates have to be capped or you will be out purchasing a new graphics card (possibly a new computer) when this one burns out. The we can worry about the screen size choices.
I also use 1920 x 1080, but I do not play sims games on laptops.
Nvidia Control Panel - Create a profile for the correct executable, that's TS3.exe for Patch 1.69 but TS3w.exe (with the "w") for1.67. Set vertical sync to On or Adaptive, whichever one works, Triple Buffering to On. These settings only work in full screen mode. If that still doesn't lock things at or below the refresh rate of your monitor, most are 60 Hz so 60 fps but some can run higher, or if windowed mode is required, then we move on to Nvidia Inspector.
Nvidia Inspector - Requires the application to be downloaded and installed. It should recognize Sims 3 for you as a usable profile. Verify that Vertical Sync is forced on, it should be inheriting this setting from the Control Panel, and explicitly set the Frame Rate Limit in the same section of settings to 60 or whatever the refresh rate of your monitor is.

Many players on Win 10 must play in windowed mode to avoid screen tears (or because they want to) and find that Windowed Borderless Gaming is very helpful.
