Phoronix: Intel Linux Driver Almost Neck-And-Neck With Windows 8.1

Intel released a big Windows graphics driver update that for Haswell hardware now provides OpenGL 4.2 support -- while the Intel Linux driver just hit the milestone of OpenGL 3.3 support. To see how the latest Windows and Linux Intel graphics drivers compare, I ran some new benchmarks on Windows 8.1 against Ubuntu 13.10 to see how the performance pans out in various OpenGL game benchmarks and other graphics workloads.
