    Is there any improvement in performance using the UWD driver? Or why should anyone switch to it? Does anyone have any data or has benchmarked it already?


    Thank you in advance.

    There is no improvements. UWD is just another way of creating and deploying the bundles with drivers.

    UWD is not a term anyone else seems to use. Officially those drivers are called DCH.

    Microsoft calls these new types of drivers bundles UWD. NVIDIA calls them DCH. Realtek calls them UAD.

    DCH(U) is actually present as an abbreviation in that linked MSDN article. Intel also uses DCH. Never seen UWD used as an abbreviation anywhere in a Microsoft document. They like to spell out "Unviersal Windows Drivers", and use "DCH(U)" to refer to the design behind it, but not spotted the acronym in an official document.

    I guess I'll stick to DCH.

    Hi,

    Standard (NVIDIA) = Legacy (Microsoft & Intel) = HDA (Realtek)

    HDA = High Definition Audio


    DCH (NVIDIA & Intel now) = DCHU (Microsoft) = UWD (Microsoft & Intel before) = UAD (Realtek)

    DCH/DCHU = Declarative Componentized Hardware Support Apps Universal API compliance
    UWD = Universal Windows Driver
    UAD = Universal Audio Driver


    Standard drivers use Win32/Legacy apps
    DCH drivers use UWP apps downloaded from Microsoft Store

    UWP = Universal Windows Platform


    /!\ DCH Drivers are only for Windows 10 64 bit 1709/RS3/16299.x or more recent /!\

    Then we will be the ones who nailed UWD abbreviation and will get royalties.
    But seriously, main this is to understand the meaning behind the words.

    Microsoft likes that combination - Universal Windows: Universal Windows Platform, Universal Windows Driver.

    PS A sudden thought. I know an example when completely different types of application are called with one name - XAML. Both UWP apps and WPF apps use kinda the same design - XAML-files - for UI representation. But beside that both types of apps are based on absolutely different platforms - WinRT for UWP and .Net Framework for WPF. And when people write "I hate XAML apps in Windows 10" they mean "I hate UWP apps in Windows 10". For me as developer it is sad a bit because XAML itself is fantastic feature which has nothing to do with the bad behaviour of UWP apps.

    i tested personally on both cards, there is no difference on performance or stability, i don't have any videos because i don't have the time to edit like the kind of benchmark videos people like, you have to take my word or test them yourself too. if you opt for the last option i can guarantee you is a waste of time.

    I'm pretty sure the only difference is the nvidia control panel. If nvcp was more responsive or loaded faster, I could see a reason for using them but that doesn't seem to be the case.

    i literally use them due to all my other drivers that require an "app" use them. So all my driver apps are in the same place.

    ocd-much.

    realtek - intel - nvidia.

    of course theres also the futureproof thing. in the end theyre all gonna end up there anyways so says poppa M$
