Thanks for your reply. Upon opening Armoury Crate, there is no GameVisual button - as in, the button on the Asus guide I consulted here
https://www.asus.com/support/FAQ/1043607/#a1 is not on my version of Armoury Crate at all. Unfortunately, this form will not allow me to post pictures of the issue for some reason, but is GameVisual only available on certain versions of Armoury Crate?
I am also unable to locate Optimus/Gsync modes, nor can I find Color Settings in the Nvidia Control Panel (mine only has the header task "3D Settings", whereas it appears that the Color Display setting should be under the task "Display", which is nowhere to be found on my end.
