Question / Help Video Adapter Grayed Out

[BeyondModern]

I installed an old GTX 660ti (it's all I have at the moment) in an effort to take some load off of my 970 while encoding/rendering w/NVENC and DX11. However, whenever I load up OBS, it defaults to using my 970 for rendering, and doesn't utilize my 660ti at all.

Under "Advanced" in settings, Video Adapter is completely unusable. The dropdown itself is grayed out, despite the log saying that it found the 660ti.

Any possible way I can fix this?

It's not implemented yet. Only way to get OBS Studio to utilize your 660Ti is if you set it as your primary monitor.

That option is not yet available in OBS Studio. To do what you're asking, I think you'll have to force OBS Studio onto the other graphics card using the Nvidia control panel (or try @Joe33345's suggestion). However, I don't think you can effectively use Game Capture across two graphics cards unless you use the "Multi-adapter compatibility" option, but that tends to introduce performance losses.
