Re: Freezing in island Paradise make game unplayable (update)
@Globularity The world of Isla Paradiso is so broken it won't run properly on any system. (The content that comes with IP works fine.) The solution is to play in another world, or edit IP or borrow a fixed version from someone else. Here's one you can download, along with instructions for the necessary edits if you'd rather do it yourself:

The other potential issue with your system is excessively high framerates. An Nvidia 1060 can produce rates well into the hundreds if fps isn't capped, and the limiter built into TS3 doesn't work. You can see your in-game fps by bringing up the cheats console (crtl-shift-C) and entering "fps on" without quotes. A number will appear in the upper right corner, and it should never exceed the refresh rate of your monitor. There are a number of tools you can use to manually cap fps. Let me know if you'd like instructions.
Sims 3 does work, and it runs very well most of the time on systems like yours, once a couple of small steps (like the above) have been taken. If you're having other game issues, feel free to start a new thread describing them.
