    Is the "no optimus = no quick sync encoding" correct statement ?
    (for laptop that use nvidia vcard and doesn't support optimus obviously)

    Quick sync needs to use the Intel IGP. So if the Intel IGP is inaccessible, then no Quick Sync. If the nVidia GPU is the only GPU you can see in the device manager, than the Intel IGP is inaccessible.

    Optimus keeps the IGP accessible. Old style nVidia GPU switching does, too. Also both versions of AMD's current GPU switching allow Intel Quick Sync.

    Yes I think there is a way you can access IGP and use Quick Sync if you have no Optimus. I could be wrong though since I only skimmed through the articles. Lucid have made a software that use the discrete GPU in everything except video transcoding, which Lucid let the IGP handle. It is called Virtu-d mode.

    What is so funny about this, is that it looks to me that you actually get a small performance boost :)

    Read about it here:

    Virtu d-Mode puts discrete GPUs first, QuickSync second - The Tech Report

    virtu still needs the ngpu to be muxed to the igp.
    what it does is use the igp instead of the ngpu(which it defaults to) when doing video transcoding.

    so no if you dont have optimus, quick sync wont work even with virtu
