I need help I'm confused


New Member
so i can stream a game obs thats good but when i add a new scene and then a new game capture I cant see the screen and to give more info i can stream, i stream minecraft and it works perfectly fine but when i try again on another scene and source it docent work, I did try the display capture that worked , and i already changed obs to power saving in the display settings on windows to see the display on my first game capture, so I'm really confused is there a way to fix it? because this is just frustrating me.
i stream on twitch
so does this mean i can only have one game capture or multiple? or for every new game except for the game i already have i have to change the game?

p.s im new to streaming
