    WDDM 1.3 AND/OR WHQL Drivers ?


    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?

    Those are 2 different display devices, one on MB the other one for discrete GPU. Each one needs own driver and yes, updating any driver will override old one and even more likely uninstall older one. If you are satisfied how everything works, better leave it alone.
