    WDDM 1.3 or/and WHQL ??


    HP OEM Lap: eo15tx
    OS :Windows 8.1
    Current GPU drivers:
    AMD 8670 : Catalyst 14.4 WHQL
    HD 4000 : WHQL Version 15.31.9.64.3165 (64-bit)


    I can see two WDDM 1.3 updates for HD4000 and AMD 8670 in Windows Update.


    Does the WDDM 1.3 drivers overwrite the existing drivers or is it supposed to be installed alongside existing drivers?

    It will overwrite the existing.

    Also just because WU says there is a driver update, you don't have to update if things are working properly.
