Question / Help preview black screen NO LAPTOP

[erutharos]

when i start OBS the preview for my game capture its enabled but i have a black screen. if i maximize the game and then minimize it y see a frozen image of my game.


pls i need to see the preview running with my game minimized.

Games usually pause the process of rendering graphics when they are minimized to taskbar to free gpu resources. I think it simply may not be possible.
You can try to run game in borderless window but im not sure it will work and may have bad impact on game capture performance

it happens again with lord of the ring online too, it is streaming but only sound and a black screen.

this is the log:
