By the way, for those who are having problems. I have a 1080GTX and the GUI was running incredibly slow. When it was displaying the mesh, either static or skeletal it worked fine in the view port, but only if it was docked in the main panel. It was so crazy slow I couldn’t work. I was kicking myself that my 1080GTX would scream, but it was dog slow.
Solution:
I added the switch -DX12 to my executable: UE4Editor, and now it’s amazing.
