High CPU overhead seems reasonable for HTML5-based games. Introducing a DOM can only make things slower relative to a leaner (native) engine.

For reference, I'm on a late-2015 laptop (XPS 13 9350) with integrated graphics, but the newer i3 gives me perfectly fine performance.

Canvas doesn't have a DOM, for what it's worth.

Oh, duh.

Still, javascript.
