Got ~8fps increase on the Tempest game I've been working on. It went from playable in Chrome, to very playable in Chrome, and still unplayable in every other browser :(<p><a href="https://github.com/mrmekon/tempest-cljs/" rel="nofollow">https://github.com/mrmekon/tempest-cljs/</a>
I ran a before (version 16?) and after on the Asteriods canvas benchmark (<a href="http://www.kevs3d.co.uk/dev/asteroidsbench/" rel="nofollow">http://www.kevs3d.co.uk/dev/asteroidsbench/</a>).<p>Overall, my score improved. The improvement wasn't uniform across tests though - some tests sped up a bunch and some actually got worse.
