A large amount of tabs cannot be the sole reason for 60% CPU usage. That's way too high. Chrome can easily keep 100 tabs open with minimal CPU usage.
A possible explanation for such a high usage is that one or more of those tabs are doing something computationally expensive.
You can find out which tabs are using the most CPU by pressing SHIFT+ESC (it opens the browser task manager).
Once you find the tabs that are using the most CPU, try closing them one by one and see if the gesture delay still happens.
Another possible cause is that one of your "RUN SCRIPT" actions is running a script that's slowing down AutoControl as a whole.
You can try disabling those script actions temporarily and then do an "Emergency repair" in order to stop any running script.
If the gesture delay disappears after that, then the culprit might indeed be one of your scripts.
Please let us know you findings.
