    Hi Guys,

    Hoping you can help. I'm aware of WDDM and how it works but not to the extent on how it would affect OS performance.

    I'm looking at updating my W7 installation to W10 but Intel only provide legacy driver support on my Sandy Bridge processor - would this make any difference to my W10 experience as regards viewing HD videos on Youtube or the like?

    I'm on a hybrid laptop with Intel HD 3000 graphics and an nVidia 525M GPU but the display always defaults to the Intel graphics for standard OS use.

    Will nVidia Optimus work properly given the older Intel graphics on Windows 10?

    Also, stupid question - but if I default my internet browser to run from the nVidia GPU will that mean Youtube and any other resource demanding sites will run from it?

    Thanks for reading and hope you can help.

    Windows 10 comes with no accelerated video drivers in the box but will probably install its own basic WDDM driver from Windows Update (D3D accelerated but no OpenGL support). So it should work, in theory.

    The issue with Optimus laptops is that the Intel GPU is the only one that is directly wired to the screen. The NVidia GPU just does the heavy lifting and writes the result into the framebuffer of the Intel GPU. So it relies on the Intel GPU to be working correctly.

    You could do a full backup of your Windows 7 install and give it a try I suppose.
