Cannot see my Huntsman TE using analogue in game mode

Ok, I received my new Huntsman Tournament edition yesterday and I really like the typing experience on these new linear optical buttons. The only criticism is the lighting though the keycaps do not match the intensity on my Viper Ultimate; in day light conditions I clearly see the lighting on my mouse but the keyboard not so, also some of the text seems to be squeezed onto the keycap with inconsistent font density 'prtscr', 'home', 'pause', 'pg up', 'pg dn' and looks quite ugly.

But when gaming (Gaming mode enable in-game) I do not get the analogue experience. Movement keys work like digital keys and I do not see any benefit at all.

I read on Reddit there was an option to alter the actuation levels for the keys, but I do not find this!
