Question / Help Settings > Video > Video Adapter not detecting all graphics cards

[Spirit]

Hello everybody,

I have been streaming for a while now but I have a problem with some lag spikes. I stream Warcraft 3. When I play it without streaming I get no spikes whatsoever. Also it is not my internet; I am not at home now so I cannot provide a speedtest link, but the download speed is 20Mbits+ and the upload 10Mbits+.

Please see log for my specs.

As can be seen, the Intel HD is being used for streaming. I have a switchable graphics card in this laptop, it can switch between Radeon HD 6770M and Intel HD 3000.

When I go into Settings > Video > Video Adapter, I can only see the Intel HD 3000. I looked at this thread https://obsproject.com/forum/threads/video-card-not-an-option.8105/ and did manually make both the 32 and 64 bit versions of OBS.exe run on High Performance in Catalyst Control Center's "Power > Switchable Graphics" tab.

Nevertheless, I can still only see the Intel HD 3000 card in the Video Adapter drop down menu, and the log says that that is the one being used indeed.

Any ideas?

Thank you.

Note about log: the video encoding settings in this log I have not tested, they are all lower than my usual settings. When I get home I will mess around with settings to find out at what point the lag spikes start happening. I provided this log more as a reference for my specs rather than my OBS settings.

This is a problem with AMD laptops with switchable graphics, with no way around it that anyone has managed to figure out yet.

Hmm.. Do you know if I can completely disable the Intel HD 3000? If I disable the driver in Windows' Device Manager, then it seems to disable both cards. (I have two drivers under "Display adapters". If I disable either one, then my resolution changes and it's obvious that neither cards are working.)

Is there perhaps an option in the BIOS to disable the Intel one?

No, we've tried literally every solution we can think of, but it's something in the AMD drivers that prevents OBS from seeing the AMD GPU. Jim has tried everything he can think of to try in order to get AMD laptops working properly, but it can't currently be done.

That's pretty sad.

Ah well.

Thank you very much for this lightning fast response. ♥ OBS! :)

Hmm, actually... I continued reading about this issue of switchable graphics...

Many people seem to report that when they set CCC (Catalyst Control Center) to run certain games on their higher performance card, the games still only show the integrated card in their in-game graphics options, EVEN THOUGH THEY ARE RUNNING ON THE HIGH PERFORMANCE CARD (they confirmed this through observing the FPS rate for example, where it would be noticeably lower with the integrated card than with the high performance one).

Someone posted that only the integrated card has access to the display, so couldn't this be the case with OBS too? That the computation happens on the high performance card, but eventually is displayed through the integrated card, and so it is the integrated card that is present in the options.
