What is RenderViewFamily and how can it be optimized?

I am currently using 4.19 with the Forward Renderer and using MSAA and Instanced Stereo Rendering for VR. When I use the console comand “stat.scenerendering”, the primary GPU consumer is the RenderViewFamily, and I have no clue what that means or how I can optimize it. The game runs fine in VR: between 90-100 FPS, so I am more just curious what this is and why it takes so much rendering time. I have looked on the forums and multiple people have had this same question, but never received a clear answer. Any information would be much appreciated!
