Re: The Sims 3 ultimate fix patch for version 1.69 final version
@mcmike89 I take it you've still been using the built-in Control Panel? (V-sync and triple buffering are both features of CP.) It's the first tool to try since it comes already installed with your graphics card driver, but it isn't always the most reliable one to use. You can instead try Nvidia Inspector, which is a free download, and use it to explicitly cap fps at your screen's refresh rate. Settings for Inspector are in the same post I linked earlier.
If that doesn't work, try RivaTuner Statistics Server, which works with any card and in windowed as well as fullscreen mode.. Again, use TS3.exe to create a profile for the game, and set the proper fps limit. Unlike CP and Inspector, RTSS does need to be running while you play, so be sure minimize it rather than closing it entirely. If you need a screenshot, let me know, but it's a pretty straightforward app to use.
Also, be sure to click the download link about halfway down the page, not the one in the upper right corner, which will be some kind of ad if you don't have an adblocker.
