Intel Haswell Linux Performance Remains Mixed Against Windows
Plot3D on Mesa 9.1 in Ubuntu 13.10 claimed better performance than Windows 8, but the numbers dropped with Mesa Git, due to more OpenGL functionality being implemented and thus the correct rendering.
The Linux performance for Furmark falls short of the Windows driver's abilities.
GpuTest's Triangle test workload was definitely in favor of Windows 8 but the Linux performance has made much headway with the upgraded Mesa.
The Pixmark performance tests are close between Windows and Linux when using the upgraded Mesa 9.3 development code.
While the Windows Intel Haswell driver is still winning in the more advanced OpenGL benchmarks/games, the open-source Linux driver continues to make progress in its OpenGL support and slowly but surely catching up to the Windows driver with regard to its features and performance. We'll keep monitoring the situation so stay tuned to Phoronix for more news articles and benchmarks on Intel's open-source Linux graphics driver.
