Unreal Engine 4.16 Preview

I just watched the pre-recorded stream about UE4.16 preview. it was a great stream exposing all of the little details!

Inquiry] One feature i noticed by chance in the video was the “asset audit window”. Because my project’s performance actually has dropped to a big low (28-30 fps) and i don’t know how to get the performance back up. I’m pretty sure my assets are fine, but my blueprints however i think might not be optimized correctly. I was thinking is there a way to have your blueprints audited as well? to know what process are taking up system recourses. i’m not sure if this has already been asked.

thank you if anyone could shed some light on this.
