How can i know what type of graphics device is used and if it has WDDM driver or not?

you can check the installed hardware on Windows using device manager. http://windows.microsoft.com/en-us/windows-8/where-is-device-manager

WDDM (Windows Display Driver Model) refers to a standard for video card drivers that's in use since Vista. As far as I know all display drivers for Windows 8 have to meet that standard. So if the card works and has a driver, it supports WDDM. Most manufactuers also list taht as a 'feature' on their specs/support page.

How can i know what type of graphics device is used and if it has WDDM driver or not?

Another method is to use System Information tool (msinfo32.exe)  Components \ Display.  Then you can search for the driver(s) mentioned there in  Software... \System Drivers  or  Loaded Modules

BTW it looks as if the Find tool is unreliable.  I can find things that are listed which the Find inexplicably can't?  YMMV.

And here's a Powershell query that shows more of the same

Get-CimInstance CIM_VideoController | fl *

strangely it doesn't show the System driver that msinfo32 showed as "Driver"

WMIC can show me that but it only calls it a  "Kernel driver"

SysDriver where (PathName like "%igd%") get /format:list

I guess the other ones are WDDM?  Shown by Powershell as InstalledDisplayDrivers (same set as shown in msinfo32) but I haven't figured out what we could do with them.

FYI
