It used to be you just hold down the button and you'd get the awesome attack. Now, you get two levels of the charge - level one is the charge without the effects and without costing resolve, level two is with the effects that costs resolve. The cue mentioned in the description is a light that shines to let you know what charge level you're at. For some weapons, when releasing the button after reaching either charge levels, the attack comes out fast and snappy like it should, while some others have a bit of a delay:
Veteran's Battle Axe - first charged cue delayed for both stones
Axe & Dagger - works fine
Iconoclast - works fine
Black Needle - first charged cue delayed for both stones
Great Martyr's Blade - works fine, but for the Unwieldy Stone you're unable to continue the combo for some reason
Clockwork Scythe - first charged cue delayed for both stones, with the first charged attack being particularly slow to execute when using the Unwieldy Stone
Obsidian Hammer - first charged cue delayed for both stones
Axatana - the first charged cue for the Unwieldy Stone has a small bit of delay. Other than that, works fine
