I’m trying to standalone debug (i.e. no editor) a scene with a simple box on it in VS2013. Everything compiles just fine but every time I try to launch debugging in Development or DebugGame mode (Win64, UE4 checked out from GIT release branch 4.6) I get a black window.
The game seems to start, CPU spins to 30% and the log just says

but nothing is shown. I even edited DefaultEngine.ini to drop potentially-expensive optimizations.
If I run the scene into the editor or launch it standalone from the editor it works just fine and the box is shown.
