graphics output API for OBS capture.

[goofyseeker311]

do you happen to be using "overlays" instead of directx or opengl as render API.
OBS application capture outputs only black when the xcom borderless full screen mode is on.
maybe window capture is the only mode it will work on. not even exclusive full screen will work.
audio capture works just fine with OBS. and the game source port works just fine itself.
