Win 10 requires WDDM (check from Win 7)[edit]

According to Verizon, Win 10 minimum requirements include WDDM (1.0 or better?)

  • Graphics card: Microsoft DirectX® 9 graphics device with WDDM driver ;
Start+R | dxdiag | Display | Drivers: {look for any mention of "WDDM"}
(Start+R | dxdiag | System: {look for any mention of "DirectX")
  • Processor: 1 gigahertz (GHz)
  • RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit) ;{note that a 32b program usually wastes half of any 64b RAM
(Novice explanation:
b=bit; B=byte=8 bits;
A '__-bit memory or machine' means that a 'word' in that system is __ bits.
A word is usually 2, 4, or 8 bytes. = A word is usually 16, 32 or 64 bits.)}
  • Free hard disk space: 16 GB
  • A Microsoft® account and Internet access ; see MSN, OneDrive, Hotmail, etc.

WDDM 1.3[edit]

Article needs update. http://msdn.microsoft.com/en-us/library/windows/hardware/dn265512(v=vs.85).aspx

- handle resources that are shared between integrated and discrete GPUs.

YUV format ranges in Windows 8.1 Preview An interface that's used to signal user-mode display drivers that video inputs are either in the studio luminance range or in the extended range.

- Wireless displays (Miracast)

- Multiplane overlay support


Supposedly Fermi-based Nvidia GPUs should be 1.3 capable given Win 8.1 and new drivers.
