About Smart Smoothing minimum framerate

Does Smart Smoothing work if you are not at 1/2 framerate?
E.g. Would it work between 30-44 fps on 90hz with Smart Smoothing on? Or do you need to be locked at 45+?

Thank you.

My understanding is that your “native” framerate needs to stay above 1/2 of the refresh rate, otherwise Smart Smoothing is disabled. So in your case (90Hz framerate), you need to keep it at or above 45 fps ALWAYS, so you should probably try to aim for something like 60 fps, so that ss stays enabled.
