Thanks, I've confirmed the missing fade to black when sleeping only happens when post processing is set to the lowest setting. I've fixed it so that won't happen in the next update.
Also, much of the overall performance issues is that I still need to add LOD to the trees and consolidate mountain meshes, which should greatly help your laptop to not be a BBQ grill.
I've found that the view distance has the greatest affect on performance for me because it greatly reduces the amount of trees and mountains that render.
