Yes, it's still a functional limitation of how SLI works.
I don't know of any plans to "fix" it as it isn't really an OBS issue to fix. It's just a side effect of how SLI functions. Jim gave a detailed explanation of what's going on in that other thread you necro'd.
Correct, a capture card wouldn't be affected by SLI. It's one of the rare situations that a single PC setup with a capture card might make sense.
thanks so mutch for the help :DThe capture card wouldn't be affected by the SLI issue whether it's in your main PC or a separate, dedicated encoding PC.
