You can do this with third-party GPU programs like MSI-Afterburner and others where you can manually set your framerate to whatever your monitor can handle in relation to its refresh rate. This might not seem like an optimal solution since 30 FPS appears "jerky" if you are used to 60, 100 and 200 FPS on most games, but once you get used to it, it actually becomes the preferred frame/tick rate because then the game play experience is butter smooth -- remember it is not the maxium frames you can render, but the LOW END number that determines smoothness -- And a side benefit is 30 FPS doesn't tax modern video cards at all. Remember, 23.97 and 29.97 are standard frame rates for full motion video (movies and games) on TV, so running at 30 FPS should feel no different.
