So I am probably being an absolute noob and missing something really important, but whenever I try to start streaming it just gives me a black screen. I have added the game i am trying to stream (OpenTTD) to the global sources list, both OBS and OTTD are set to use the same processor in the NVIDIA control panel (i am on a desktop anyway, not a laptop), my antivirus is not intruding on anything and I have flicked between OTTD and OBS-what am I doing wrong?
