@RaisinsGirlELou Many people have reported the Nvidia fps limiter is broken. Many people with ATI (AMD) have used MSI Afterburner. As this is a third party program it should work with Nvidia chips also.
Hey @roberta591 I thought you should know that the OP got a lot of help this afternoon over at the forums (as in, way more than I could have provided). It turns out to be as much as hardware issue as anything, as in, neither the processor nor the graphics card is good enough to run TS3. Given the consensus from the experts over there, the OP is understandably disappointed and may not be back here looking for any more help.
Here's the thread, if you're interested:
