Intel Broadwell Iris Pro Graphics: Windows 10 vs. Linux

The Unigine tests had issues running under Windows 10, so this Windows vs. Linux comparison had a few older OpenGL tests than usual, based upon the selection of cross-platform OpenGL tests we have available for use. With the old Nexuiz game, Windows 10 was leading over Fedora 22 in both of its configurations by about 18%.

The oldest test run was OpenArena, which is an ioquake3 era game still loved by some given recent comments about it in our forums... Here the OpenArena performance was about 55% faster on Linux than Windows for this Intel Iris Pro 6200 graphics system.

A look at OpenArena's frame latency, given that the game exposes the information in a suitable manner for parsing by the Phoronix Test Suite.

Xonotic is the most interesting Linux/Windows game ran for this inaugural Windows 10 comparison given its one of the more demanding OpenGL games and runs well on both platforms. Starting off with low image quality settings, the Intel Windows OpenGL driver was faster by just over 10%. Of course, with the frame-rates of this game on the Broadwell graphics at low quality settings, gamers wouldn't really notice this difference at 1080p.
