Oh, and I think the Shadow Min Bias could even be lowered a bit. It's 0.8 now, and you can take it down to 0.25 or 0.3 or so. Even 0.1 if you want.

And DEFINITELY uncheck Reflection Lite Multi. Don't ever use it or Reflection Kd Multi. I have no idea why SM still includes them. Outdated and may even be detrimental to your render, especially if you have reflections.
