Indeed, Apple's Mac OS X QuartzGL framework (GPU accelerated drawing/rasterisation) is slower than the equivalent CPU-based Quartz framework in may cases. You're being shafted by downvoters who don't really know what they're talking about.

For that you'd probably want to dig into WebKit.framework — the private WebPluginController & WebPluginDatabase classes look rather interesting.

Hi Ryan, That's pretty neat! An unfortunate side effect is that running Mobile Safari unsigned negates the 'dynamic-codesigning' entitlement, which means that Nitro is disabled. That said, a WebGL-enabled UIWebView running in your own app w

The argument that WebGL "competes" with OpenGL-ES, to the detriment of Apple, makes very little sense to me. You only need to look at the number of engineers Apple has contributing to WebKit & new web standards (CSS transitions & an
