While the use of continuous slideshows is strongly discouraged due to their impact on CPU usage, they are possible with Cycle2 by setting the easing and timeout options as shown below.

<div class="cycle-slideshow cycle-autoinit" 
    data-cycle-fx="scrollHorz"
    data-cycle-speed="3000"
    data-cycle-timeout="1"
    data-cycle-easing="linear"
