Well, the renderer used in the log is what's important. The Display Info is just the name we get from the system.

If the VGA port is actually linked to the Intel card, that would confirm your feeling that it's slower, since Resolume would need to copy the texture from the Quadro to the Intel.

The heavy lifting is always done on the graphic card that has the GUI on it. This is why using multiple GPUs is not so efficient. Your output texture is calculated on the first GPU, and then needs to be copied over to the others. It's much more efficient to use a single GPU with multiple outputs or a graphic extender.
I never wouldve guessed that using an extender would be more efficient. Thanks for clearing this up Joris. It makes perfect sense!
