WDDM vs Intel Driver

[Promus]

What are the major differences between the two? Does the wddm work better with windows or would intel? Does the intel one unlock all the extra features of the item? All the articles I have seen are back from vista days so, how does it apply nowadays?

Is it case of one or other, I think intel drivers support WDDM

Windows® 10 drivers will include support for Windows Display Driver Model (WDDM) 2.0.

I don't think it's one or the other. I believe WDDM is another layer between the OS and the graphics card. You still need WDDM (which is baked into Windows anyway), in addition to the graphics driver (whether it be Intel, Nvidia, or AMD). That's my (admittedly limited) understanding of it anyway.

When windows is first installed it generally uses a wddm driver. In my old laptop this limited opengl to 1.2 or something ridiculous while the [assumed] intel driver let it use 2.1

I am curious as to whether a plain old wddm driver would unlock thinks like quick video sync or dynamic frequency or whatever the features may be. If it would then I don't see nay reason an intel driver would be needed but, I just don't know

windows drivers are generally generic, match the features the basic model of the hardware has whereas Intel ones may have more up to date feature support. Ideally, best idea is use the drivers that come with the hardware and only use the windows drivers that come with OS for things you cannot find drivers for.
