Intel Graphics: Windows 7 & Windows 8 vs. Ubuntu 13.04 & Fedora 18

Windows 7 SP1 didn't run with Xonotic on the Intel HD 4000 driver tested. With the Fedora 18 results, there isn't anything new to add over the Ubuntu 13.04 numbers. Windows 8 for this Intel OpenGL testing is still faster than the Linux results.

Overall, for the common Intel HD "Ivy Bridge" graphics drivers, Windows 7/8 is still generally faster than the latest Intel Linux graphics driver. There isn't much more to add than the earlier conclusion. Intel's Windows driver also remains ahead with OpenGL compliance (OpenGL 3.3/4.0+ is still a ways away for the Linux Mesa drivers) and other features. As was shared recently at the GDC2013 conference, Intel Windows driver developers are also reportedly working on a more-optimized Ivy Bridge driver for release soon. It will be interesting to see how much faster the forthcoming Intel Windows driver release is for our benchmarks, but Intel has reported that it will be a measurable gain. Unfortunately, there hasn't been any word out of the Intel OTC crew about any major Linux driver optimizations ahead for Ivy Bridge.
