Lumen reflections not working correctly?

Hi there,

I am learning Archviz and have imported my model from 3DS Max. I have added windows to the build and the lumen reflections are extremely poor and not acceptable quality. I have been through hours and hours or tutorials and tweaked settings and noticed that when i change setting when following tutorials that i don’t get the same results. I am starting to wonder if its a lighting issue or maybe something else.

I have uploaded an image with the reflections i am talking about and what they should look like along with my settings.
