Just discovered that you can't even map keyboard controls to on-screen controls unless you use a Asus branded accessory. I am using a USB-C Plugable Display dock to capture/output the screen. Was hoping I could connect a physical mouse and keyboard and enjoy playing my games that way.
Locking down software features behind really expensive hardware that only works on one device is pretty lame. Nvidia did the same crap with the Nvidia SHIELD Tablet.
