Not sure if this is the correct forum…
I’ve downloaded this demo and noticed it crashes when trying to bring in a tree or object from the meshes into my map. It also takes forever to load the demo maps. It took about 30 minutes to open the Showcase map which was extremely small. Is it the KiteDemo itself?
My hardware setup includes:
i5 4690
16GB Ram
Sapphire Tri-X R9 290
Windows 7 64-bit.
Could you probably post your log -> documents-unreal projects - project name - saved - logs - the latest file 
Also set the quality settings to “low” and try it again.
Alright, I would just like to point out to anyone having this issue. If you have AMD’s Raptr or a similar program from nVidia you might run into the issue I was having. I closed Raptr and everything loads as it should, quick and no issues.
