Ubuntu 14.04: Intel's Haswell Linux Driver Comes Up Short Of Windows 8.1

While Unigine Heaven and Valley failed to run properly "out of the box" with Ubuntu 14.04 for the Intel driver, the Sanctuary and Tropics tests rendered fine on both platforms. The Intel Mesa Linux graphics driver for the older Unigine Sanctuary and Tropics tests were running at less than 70% the speed of the Windows 8.1 driver.

The Xonotic first person shooter gaming performance for the Intel Core i7 4770K was close to the same speed between Ubuntu 14.04 LTS and Windows 8.1, but the Microsoft OS did have the highest frame-rates.
