Grainy/Noisy SSR Reflections

Seems UE4 has some shortcomings with good reflections. SSR tends to give very grainy/noisy reflections. Turned SSR off and Reflection captures don’t look that bad. Cranking r.SSR quality to 4 offers some impovements but drops framerate. Setting effects to cinematic improves it but its not perfect or as good as I would want it. Guess planar reflections and some sort of cheats to get some good results. Planar reflections support dynamic objects, right?
I am wondering if SSR can be improved in future or is there something being planned for better reflections in ue4 future releases?

Found this:3D Modeling & Texturing: [Unreal Engine 4] Improving Screen Space Reflections

There seems to be some improvements with better framerate.
