I'm very new to this field, this might be a stupid question... So I downloaded the SDK 1.4.0 and unzipped it. After build the Samples/Projects/Windows/VS2015/Samples.sln solution in VS2015, I tried to run OculusRoomTiny (DX11) sample but only got black screen... What are the possible reasons for this, anyone has any ideas? Is there any specific settings I need to change in Visual Studio?
