"Note, however, that it only accepts integers... so if you have your screen refresh at 75Hz then you have a problem because you can't limit to 37.5fps."

So you are saying that you MUST set the FPS limit to HALF of your refresh rate?

No, you can limit it to anything, but unless you use R/2 or R/3 or R/4 (etc), where R is your refresh rate, then the results won't be much of an improvement on normal VS+TB.

So if your refresh rate is 90Hz, for example, then you should set it to either 45 or to 30. If you set it to 45 then you should enable triple buffering unless you're certain that your machine can manage a minimum of 45fps at all times. Same goes for 30, for that matter.
