Best Extension to Fix Choppy Scrolling in Chrome

Choppy scrolling usually comes from the page or the computer rather than the scroll animation, so an extension rarely fixes it. Check that Settings > System > "Use graphics acceleration when available" is on, update your graphics driver, and turn off extensions one at a time, since some slow down every page. Close heavy tabs or turn on Memory Saver in Settings > Performance. Chrome smooths wheel scrolling by default; if someone has disabled it, the flag at chrome://flags/#smooth-scrolling, where your version lists it, turns it back on.
