So I played around a bit and found the "create virtual input" on the input settings page.
Seems as if it creates another input with the same settings as the original. This seems handy.
But is there anything else with virtual inputs to consider and watch out for?

Having trouble finding any substantial information in the manuals and vmix tutorial videos (probly just me lousy att search...).

Thanks, but this video does not really explain the virtual inputs in any detail more than a easy way to duplicate a input to add effects. And maybe this is the best use case for them?

I was wondering about how the work when it comes to performance vs using regular inputs, other use cases, problem areas etc.
