Bug Report Black screen game capture

I need some help, when i use game capture i get black screen on Preview Stream.

I have a notebook, whit a radeon 6770HD. I alrealy saw some people whit notebooks having the same issue. Anyone alrealy know how to fix it?

ps: I alrealy put obs to run in high performance, don't solved the problem.
ps2: I don't even have the option to make on Settings > Video to use the radeon gpu.

Ah, yes, radeon laptops. Right now, radeon laptops don't seem to capture properly, and this doesn't seem to be a bug in OBS. I believe this is due to their design -- even setting them to the correct adapter in radeon control panel typically still ends up with them running on the intel instead of the radeon. I believe this is because of windowed/fullscreen mode on most 3D applications, though I'm not entirely sure. Currently, the only real reliable way to capture on radeon laptops is to run your game in a borderless/windowed mode, and use window capture with "compatibility mode" checked. It probably should have been noted in the laptop thread (I should add something for it if not)

It sucks, but there doesn't seem to be any other reliable way yet, and at some point I might buy myself a radeon laptop just to try to investigate if there are any other workarounds that can be done. Actually could you give me the exact model of laptop you have?
