Which is best for performance: enable/disable Renderer or GameObject?

    Hi guys.

    Question is simple:
    I have 2 really high-poly meshes, and I need to switch showing from one to the other....

    Which one is the best way to go? Dealing with the Renderer, or the GameObject?
    It is just a renderer based GameObject, so please, do not take into account the existence of any other components.

    Regards

    My bet would be renderer. If you are just switching the renderer on and off, Vs the entire gameObject, my bet that, will be less costly, the switch, to the engine. I would be interested in hearing more experienced opinions tho.

    The Unity Profiler (if you have Pro) and System.Diagnostics Stopwatch are great tools to get those types of answers.

    Using the Stopwatch and iterating 1 million times over toggling GameObject.SetActive() between True and False took about 1335ms.

    Doing the same thing and toggling the Renderer.enabled between True and False took about 84.4ms.

    Great to know!

    And most important, thanks for pointing out the profiler tip, I will definitely start doing that kind of testings...
