interactivity of the manipulation of the objects and the properties of the shader for cycles also available with eevee

on blender 2.8 if you open a scene full of objects and start to set the properties of the shaders in the new cycles, the visual interactivity and performance in setting the properties is always fluid and performing, while in eevee it begins to become difficult due to the loss performance ... would be useful if the same cycles interaction technique was also used with eevee
