I seem to have OBS crash immediately when I start or preview a stream with certain games. The two most recent ones that spring to mind are Probability 0 and Outland. The crash always seems to be related to Game Capture, as I can toggle off individual sources in a scene, and toggling on Game Capture causes the crash. Anyone know of a workaround, outside of using Window Capture? (These games really don't need the FPS hit of Window Capture.)
