Hi,
Not sure what's happening here but I couldn't find any answers as to what is happening.
Whenever I use Game source as a capture source my FPS drops to 10 or below. However if I capture my whole display I am able to keep 60fps no problem.
I've tried a number of configurations and none seem to work for Game source. Has anyone experienced this? How do I resolve?
