Question / Help No Multi-GPU Compatibility Option with DX Renderer

So I finally figured out how to make OBS (Studio) work with my SLI/Surround setup - for some curious reason it only properly captures the desktop with the OpenGL renderer. The OpenGL renderer works whether or not the multi-GPU compatibility fixes are checked in the config. I'd prefer to use the DX renderer however as it seems my window animations get a bit choppy when using OpenGL. Why is there no "Multi-Adapter Compatibility" box available for me on DX?

Also, another peculiarity, after turning Surround off, the DX renderer worked fine. It also worked fine when I re-enabled Surround and my displays were in the wrong order. When I righted the order however, no monitor capture - only black.

Any help is greatly appreciated. This is driving me nuts.

Below is the log file w/DX renderer.

I notice that it's using my first card. Is there a way to manually switch which card it's using? I looked under the advanced page and although there's an option to switch video adapters, it's blank and can't be configured.

This is interesting. I have the inverse, my sli rig uses the second card but only after swapping card slots. I have an sli setup, gtx760 reference card and an Asus gtx760dcuiioc in win 10 machine and for stability had to put the slower ( reference card) in the FIRST pcie slot. OBS uses only the oc second card for encoding now(as does steam link. I only discovered this after having to switch cards in slots when games and obs were stuttering.
Tldr, Maybe try swapping slots in your sli configuration.
