The open-source Intel Linux graphics driver has hit a milestone of now being faster than Apple's own OpenGL stack on OS X. The Intel Linux driver on Ubuntu 13.04 is now clearly faster than Apple's internally-developed Intel OpenGL driver on OS X 10.8.3. when benchmarked from a 'Sandy Bridge' class Mac Mini. Only some months ago, Apple's GL driver was still trouncing the Intel Linux Mesa driver
