How to set project to a max of 30FPS

Hi, I have a project that renders at a rate between 30 and 47 frames per second. It varies depending on the amount of input from the user and the generated imagery. This is a bit unpleasant because some of the visuals, like particles and instancing, keep rushing/slowing down as the FPS go up and down. Is there a way to set the FPS ceiling to 30?

In the bottom left corner of the UI, there is a small area where you’ll see FPS, you can click on the number and change it to 30.

So simple! Thanks!
