Linux 3.9 To Linux 4.9 Kernel Benchmarks: Testing The 21 Last Kernels

The Haswell graphics were working fine on Linux 3.11 and later for benchmarking purposes, but on the older kernels only OpenGL 3.1 works for the HD Graphics 4600.

Linux 4.0 seems to be the last time the Haswell graphics improved as a result of i915 DRM driver changes.

The Dota 2 results are similar with the Haswell open-source graphics support having been mature for quite some time now.
