WebGL performance issues with retina Macbook Pro

Just want to give an update to all those who followed this post some closure. I was able to get my application running above 45 FPS by simply setting the canvas option "antialias: false". This gave a huge performance gain on high density displays, and isn't necessary since high density displays provide a large amount of built-in antialiasing. Hope this helps someone else in the future.

Some things are not hardware accelerated in Chrome on Mac OSx.

Take a look at this URL:

chrome://gpu/

If you find something that is disabled, you can potentially adjust it using:

chrome://flags/

The downside, is that if you find something that works, it isn't exactly deployable. It may give you insights into where your bottleneck is though.
