Update Rate Optimization? URO 4 OR 10?

Hi All,

I was watching the Optimization talk from GDC. Linked below. They have a very interesting use of Update Rate Optimization. In blueprint we have a check box for on and off but no way to adjust the tick rate or the interpolation. This is a major optimization. Has anyone been able to optimize like they talk about? Does anyone know how to set URO to 4 or 10 like they talk about?
