    Hi,
    From our dev guy.
    Nvidia Play game use different part compare to video encode. After Pascal they use NVENC chips for video encode.
    For example, gtx1050 1 nvenc chip, GeForce GTX 1070 - 1080 2 nvenc chips, GeForce GTX Titan X 3 nvenc chips,
    In DVDFab current use only one nvenc chips, ( fulldisc need get size of converted files do decide not converted video bitrate)
    So use one NVENC chip gtx1050 vs gtx1080 in video encode, there may be about 10% speed up.
    Nvidia 2080 Turing mostly up for game and play video, not much for NVENC chips.

    So your can ran multi DVDFab.
    Or in future DVDFab add better support for parallel task .

    When concern about video Encode, order should be Nvidia > Intel > AMD .
    Only AMD not support HEVC main10 encode for now.
    But for game and other things AMD is much better than Intel, maybe sometime Nvidia.

    They mostly update for better game render first.


    yours,
    Wilson
