How do I test low framerate?

I’m using a function that uses distance and deltatime to control my camera. It seems to be working well but, I want to make sure that it doesn’t freak out if the framerate dips super low

You can use Application.targetFrameRate, and set it to some low number. It doesn’t sound like something that should be a problem though; if the framerate dips super low, things will look weird anyway. I don’t know your specific code, but well-made functions to move things that use delta time usually work with different framerates in my experience; that’s the point of using delta.
