    Hello,

    I use a radRotator to display a rotating text. It behaves good in Chrome, Firefox and IE10. Nevertheless in IE8, it seems to be like jerky. My page also has a radMenu and a radGrid. It is getting worse when the mouse goes over the radGrid and the radMenu. I already decreased the speed of the rotator which seems to be correct only if the mouse does not move.

    I checked two of your demos with radRotators:
    http://demos.telerik.com/aspnet-ajax/rotator/examples/multiplescroller/defaultcs.aspx
    http://demos.telerik.com/aspnet-ajax/rotator/examples/livexml/defaultcs.aspx

    I get the same behavior.

    What would be my options to improve the smoothness please?

    Thank you
    Gregory

    I'd like to add, after reading another post, that the CPU usage increases from 3% to 15%, with a few jumps to 20%.

    Hi Greg,

    The IE8 browser has known performance issues that are not in our control, so it is expected that the RadRotator animation will not be very smooth in this case. The same effect can be examined with the animate function of jQuery, on which the rotator animation is based.

    I would suggest checking if any of the results in this search will be useful for optimizing the performance of the browser thus achieving a smoother animation.

    Hello Slav,

    Thank you for your answer. I was afraid of this answer but I guess it is what it is. I'll try some of the tips of IE8 optimization.

    Thank you
    Greg
