As Brandon has said, it depends on your system if Angle is using DX11 or

That's probably not got anything to do with the backend choice. It runs
smooth here in Chrome/Linux.

Stuttering/Jerking/etc. is most often caused by engaging the JS garbage
collector a lot. Each time it kicks in, it stops the world for anything
between 80-150ms and nothing gets drawn during that time.
It is possible that there's a particular bug with Chrome (due to vsync and
whatnot) that you might be affected by (Brandon and I talked about this
getting somewhat worse). You should compare your demo on different browsers
(IE, Chrome, Firefox, Opera) and on different OSes (OSX, Windows, Android,
iOS). This helps you spot if you did something wrong (it's bad everywhere),
or something suboptimal you did (it's good on exactly one browser, but not
on any other), or if it's a browser bug (it's bad on only one browser).
