As it's been a while since my last Windows vs. Linux graphics comparison and haven't yet done such a comparison for Intel's latest-generation Skylake HD Graphics, the past few days I was running Windows 10 Pro x64 versus Ubuntu 15.10 graphics benchmarks with a Core i5 6600K sporting HD Graphics 530.

This article is an OpenGL performance comparison between Windows 10 Pro x64 and Ubuntu 15.10 when upgrading to the very latest open-source graphics driver stack. Atop Ubuntu 15.10 was the upgrade to the Linux 4.3.0 stable kernel and also switching to Mesa 11.1-devel Git using the Padoka PPA. On the Windows side, the latest Intel 20.19.15.4300 graphics driver was used for benchmarking this Skylake system.
