Ctrl+Mousewheel Zoom Speed Settings?

When I ctrl+click to zoom in and out in the design side of Easel on my laptop, it zooms in and out rapidly, which I love. But on my tablet or on my desktop at home, it barely zooms with each click of the scroll wheel. It it ridiculously slow to zoom in on something… What is this setting tied to? Both the laptop and the desktop have the same number of lines set to scroll per movement of the scroll wheel in my mouse settings, so it must be something else… Right?

Windows 10/10/7, Firefox in all cases.
