Question / Help problems with OBS and World of Warcraft

Hello,

i'm having some difficulties with OBS and World of Warcraft. I'm using it on my Dell Laptop with a regular PC screen attached (if that makes any difference).

- First of all, if i select "Game Capture" as source, the recording window will stay black, i can only see the cursor moving. So i have to resort to screen capture. Is there any way to fix this?

- Also, my framerate drops significantly when i'm streaming, to the point where it becomes pretty much unplayable. My laptop can definitely handle WoW (Intel i7-3612 QM, 8 GB RAM, GPUs are called "AMD Radeon HD 7700M Series / Intel(R) HD Graphics 4000"), but as soon as i start streaming, FPS goes down to about ~20-25ish. I have Resolution Downscale on 1280x800, down from 1920 x 1200.

How should i go about fixing these two issues? Thanks a lot in advance for your help!

From what i can tell, the laptop thread is about laptops with nvidia gpus, however i have an AMD GPU. That i'm unable to game capture is not that big of a deal to me, screen capture is fine. I do need to fix the massive FPS drops however.

Here's the log of a quick stream i ran just now:

Is it possible that it's using the wrong GPU here? The log says

"Loading up D3D10 on Intel(R) HD Graphics 4000 (Adapter 1)..."

but the other GPU is not mentioned. Also, in the video settings, it only lets me select the weak GPU. Could this be the cause? And if so, how can i fix it?

And another thing i've found.. So since the right GPU is not in the list in OBS video settings, i tried forcing this GPU for OBS in the AMD driver.. I managed to set it up to use the AMD GPU for OBS without any problems there, however when i opened up OBS, the video settings still only showed the Intel GPU. Monitor, as well as game capture, just produced a black screen when driver-forced to the AMD GPU. Don't know what else to try, any ideas?

Unfortunately, there are some bugs with mobile AMD GPU drivers such that game capture won't work. The only way to capture a game with a mobile AMD GPU is to use Window capture with compatibility mode.
