Greeting Experts. It looks like the WDDM (Windows Display Driver Model) has been update from 1.2 to 1.3 in the upcoming Windows 8.1.
As far as I know this basically mean that there are enhancement to the graphics driver in 8.1, and presumably that means drivers specifically for this version is required to take advantage of the new functionalities. In fact I see that there are already separate drivers for win 8 and win 8.1 in Nvidia and AMD.
What about Windows 8 drivers for older graphic cards? Can I still use Win 8 drivers in Win8.1. For example my laptop has a "Mobile Intel(R) 4 Series Express Chipset Family" graphic card that has only up to Windows 8 driver support, Intel hardly release any driver update for so I doubt there will be one for 8.1 in the foreseeable future.
Thanks in advance
