I need some help in streaming Team Fortress 2. I installed Open Broadcaster and selected 'Game Capture' and the TF2 process, but when I preview the stream all I get is a black screen. The Game Capture works for Minecraft and other games but not for TF2.
I found out what was going on. I play on a laptop that has two different graphics cards. An integrated card and a discrete graphics card. When you use Open Broadcaster make sure the game AND OBS are running off of the same graphics card. In my case, I had to go into the Nvidia control panel and manually set OBS to run on the discrete graphics card.
