Crossfire / SLI is not recommended at all, it introduces all kinds of compatibility issues (not just in OBS).

There is nothing to code - GPU drivers are simply lacking SLI compatibility hacks for applications like OBS that read frame data, and having to read out of multiple GPUs memory across a reduced speed PCI-e link will impact performance considerably if it even works. I suggest not using SLI in the future.
