I want to do a simple stream playing a video game with my camera as overlay. I have 2 monitors and set up vmix on the second monitor. I tried using Desktop Capture on my 1st display, but when I launched the game, the desktop capture only showed the desktop and not the game application. Could this be something to do with it being windowed mode? Is there a better method to stream my game?

This is a super common issue with VMix and desktop capture. The problem is almost always that the game is running in exclusive full-screen mode — that’s why Desktop Capture only shows the desktop and not the game window. The fix is simple: launch the game in borderless windowed mode (or windowed) and capture that instead. For more game day inspiration, check TonyBet Alberta. Once you do that the overlay camera will show up perfectly and you’ll get a clean stream.
