Low Poly Artifacts in Blender Cycles (Terminator Artifact)

When rendering some low-poly models in Blender Cycles we get these jagged shadows around polygons. This is what's known as Terminator Artifact and is also present in other 3D packages such as Pixar Renderman. Rendering the same model in Blender's internal renderer yields a way better results. The only way to solve this would be to increase polycount by subdivision. I also noticed that creating lights with softer shadows or increasing the amount of lights greatly lessens the impact of the terminator artifact. I really look forward the incoming Eevee realtime renderer for Blender which likely solves this issue for low poly models. Here is more information about this phenomena https://developer.blender.org/T37814 and here is a technical explanation of it: https://pdfs.semanticscholar.org/7986/ebd7b5427bbe54edb7c0c9cf674fee817933.pdf Here is other video about this issue: https://www.youtube.com/watch?v=_pvcLyHokbY
